Methodologies for Addressing the Performance Issues of Routing in Mobile Ad hoc Networks: A Review

The objective of this review article is to offer an insight into the performance issues pertinent to routing in Mobile Ad hoc Networks. This work has studied the approaches for solving the performance issues such as changes in topology, energy consumption of mobile nodes, delay, routing overhead, message delivery time, throughput, packet delivery ratio, security of networks and mobility management. To provide a perception of solutions for these issues, this study concentrates on various methodologies such as Effective Hierarchical Routing Algorithm, Link Stability with Energy Aware Multipath Routing protocol, Path Encounter Rate metric and Trust-based Source Routing protocol. Effective Hierarchical Routing Algorithm computes the route and has decreased the load of routing protocols. Link Stability with Energy Aware Multipath Routing protocol finds routes with small delay. Delivery ratio of packet in LSEA is improved on par with Ad hoc On-demand Distance Vector Routing (AODV). Delivery ratio of packets in LSEA was enhanced by 40%. To get an efficient metric for routing in high mobility situations, Path Encounter Rate metric was proposed. Throughput achieved with this metric was 30% higher than those obtained by the hop-count metric. To choose a least-cost route with security constraints, TSR was proposed. TSR has improved the packet delivery ratio, ratio of identifying the malicious nodes as well as network throughput. This review of different methods can be used by researchers to find a better solution to these issues.
