    Achieving energy efficiency in manets by using load balancing approach
    (International Journal of Computer Networks and Communications Security, 2015) Junaid A. Khan; M. Nasir Iqbal; Farooq Umer; Muhammad Adnan; Zeeshan A.Khan; Mustafa Shakir
    Mobile Ad Hoc networks have no base station and use multihop routing for transmission of data from a source node to its destination node. To make this multi-hop routing mechanism possible we need a routing protocol. We have adopted load balancing technique that can improve the overall performance for communication in a network. We have presented optimum performance for our novel protocol i.e. Energy Efficient Load Balanced (EFLBAODV) and compared it to the traditionally existing reactive routing protocol Ad Hoc on Demand Distance Vector (AODV) thus using the load balancing technique to improve the node to node communication in our network. Also our routing protocol will be energy efficient as it will minimize the communication time and overheads thus utilizing the energy resources. Some important metrics like route discovery time, route errors, MAC delay, network load, end-to-end delay and throughput have been taken to evaluate the overall improvement in the novel protocol.

    Comparative analysis of ad hoc routing protocols
    (IDOSI Publications, 2013) Farooq Umer; Muhammad Adnan; Mustafa Shakir; Izhar-ul-Haq; Mahmood Ashraf Khan; Nasir Iqbal
    Manet has become the most popular network nowadays for communication. Communication is being done without any need of establishing heavy centralized fixed node architecture. Nodes are mobile, so nodes need cooperation of other nodes to maintain route in the network. The topology keeps on changing in MANETS effecting different aspects of network. There are many aspects on which routing depend in a MANET. Many evaluations of comparisonshave been done using different scenarios resulting in different results. A variation of result may be found in different scenarios. We have briefly evaluated a comparison of AODV, OLSR, DSR and GRP protocols. A different scenario was created to evaluate their performances. This paper focuses on the performance of these protocols by four matrices namely throughput, delay, load and retransmission attempts. The overall goal was to determine the more suitable protocol for routing in ad-hoc MANET in a mobile network. Different protocols performed better in different metrics. We have carried out simulations in OPNET tool.
