However, transmitting the data through multiple networks create packet reordering issues that result in transmission delay and degrades the overall quality of services. This paper addresses packet reordering issues both for single and multiple paths with a reordering delay in the transmission system. An algorithm has proposed to mitigate the associated delay that has been simulated in network simulator 3 (NS3). The simulation results have benchmarked with the well known Earliest Delivery Path First (EDPF) method and shown better performance over the EDPF results. Moreover, the simulation has been done to analyze the packet scheduling including to measuring packet reordering delay, and reordering entropy. CBR and VBR applications have been transmitted for 1800ms from sender to receiver in a heterogeneous wireless environment created in NS3. The results show the proposed method achieved to reduce the reordering delay and reordering entropy both for CBR and VBR applications

Voice, video conferencing, graphics services are considered as IMM applications, at low cost with more flexibility in a high speed Wireless Local Area Network (WLAN) that can be defined as a high speed Wireless Campus Network (WCN). The networks' traffic flow determines the participating users work as a sender or receiver during the voice or video conversation. The IMM applications have to be kept the least data loss and maximum throughput over WCN. Packets scheduling and channel allocation mechanism are the challenging issues for improving IMM transmission and it is still an unresolved problem over WCN. This paper reviews on different exist scheduling mechanisms and channel allocation algorithms of IMM related to various applications and highlights the current issues. A new priority based scheduling scheme and dynamic channel allocation mechanisms have been proposed in this paper. It is expected that the proposed mechanisms ensure the minimum requirement of the IMM applications which will deliver QoS with the least handoff delay and minimize the call dropping probabilities for IMM applications though WCNs.

It brings numerous benefits and facilities to the society and users. However, the usage of the ICT devices and its entire life cycle produce hazardous substances including harmful CO2. Reducing the energy consumption in an individual or organizational level effected the ultimate reduction of CO2 in global perspective. Therefore, the adoption of green ICT is becoming more popular due to the increasing number of ICT infrastructures and facilities. Considering this issue in mind, this paper addresses the scenario of energy consumption in the field of ICT in a global context. Particularly, an awareness survey has been conducted among staff and students of International Islamic University Malaysia (IIUM) to assess the adoption trend of green ICT in campus. Public awareness is considered one of the most important factors to increase the adoption of green ICT in everywhere. During the group survey, a short briefing and discussion also have been conducted to inform and motivate the students about green ICT. The survey results show that some interviewees are still not familiar with this "green ICT" term and its adoption. Therefore, further motivation and influence need to be drawn among staff and students towards a sustainable environment.
Next Generation Networks (NGN) both static and mobile are expected to be fully Internet Protocol ... more Next Generation Networks (NGN) both static and mobile are expected to be fully Internet Protocol Version 6 (IPv6) based. Mobility in IPv6 (MIPv6) network was designed to provide Internet services to end users at anytime and anywhere. However, MIPv6 is not widely deployed yet due to handoff latency and other limitations leading to packet loss and Quality of Service (QoS) degradation for real time applications such as audio and video streaming. MIPv6 handoff latency can be categorized into layer 2 (L2) and layer 3 (L3) delays that includes link layer establishment delay, movement detection delay, address configuration delay and binding update or registration delay. Movement detection delay and address configuration including Duplicate Address Detection (DAD) in L2 and L3 respectively consume the highest time of the total delay. In order to reduce these handoff latencies, two solutions are proposed to focus all the delays both in L2 and L3. The first solution is the fuzzy logic technique based network awareness to reduce movement detection delay especially the scanning time in L2 in heterogeneous networks. The second solution is Parallel DAD (PDAD) to reduce address configuration time in L3. Both solutions benchmarked with OMNeT++ simulator show improvements over standard MIPv6 networks. The handoff latency reduced more than 50% and packet loss improved around 55% in L2. Moreover, in L3 the handoff latency reduction accounts for 70% and packet loss improved approximately 60%. The handoff latency is reduced from 1300 ms to 500 ms applying fuzzy logic technique at L2 and PDAD mechanism in L3 leading to overall delay reduction of 60%.

Multicast Ad hoc On-Demand Distance Vector (MAODV) protocol is a tree based multicast routing protocol that enables dynamic, self-starting, multi-hop routing between participating mobile nodes wishing to join or participate in a multicast group in Wireless Mesh Network (WMN). The mobility of mobile nodes often causes link breakage in the tree-based protocols which ...

This is due to the fact that WMNs can be permanent or semi-permanent networks. Moreover, a reliable path from the source to the destination can be maintained using an improved and better performance metrics. Currently, the most widely used performance metric is the minimum hop-count which is based on the assumption that communication links are either working well or not working at all. This assumption is true for wired networks however this is impractical for wireless networks where numerous links suffer from intermediate loss ratios, low throughput, interference and other inherent limitations. Consequently, researchers have proposed a number of performance metrics for WMNs. It has also been shown that integrating multiple performance metrics into a routing protocol is effective for attaining optimal performance since it is highly probable that a single performance metric will not be able to satisfy the comprehensive requirements of WMNs. This paper presents a technique of integrating multiple routing metrics in order to optimize the performance of a routing protocol. The proposed technique is implemented on Multicast Ad-hoc On-Demand Distance Vector (MAODV) routing protocol. Simulation results show a statistically significant performance improvement over standard MAODV for WMNs.

It has been designed to support different types of technologies for providing seamless communications in next generation network. However, MIPv6 and subsequent standards have some limitations due to its handoff latency. In this paper, a fuzzy logic based mechanism is proposed to reduce the handoff latency of MIPv6 for Layer 2 (L2) by scanning the Access Points (APs) while the Mobile Node (MN) is moving among different APs. Handoff latency occurs when the MN switches from one AP to another in L2. Heterogeneous network is considered in this research in order to reduce the delays in L2. Received Signal Strength Indicator (RSSI) and velocity of the MN are considered as the input of fuzzy logic technique. This technique helps the MN to measure optimum signal quality from APs for the speedy mobile node based on fuzzy logic input rules and makes a list of interfaces. A suitable interface from the list of available interfaces can be selected like WiFi, WiMAX or GSM. Simulation results show 55% handoff latency reduction and 50% packet loss improvement in L2 compared to standard to MIPv6.
