A Novel Technique to Control Congestion and Energy Aware Routing Scheme for Wireless Mobile Ad hoc Networks

摘要

Background/Objectives: With the increase of portable devices as well as progress in wireless communication, Mobile Ad-hoc Networking is gaining importance with the increasing number of widespread applications. Due to the special characteristics of MANET, such as dynamic nature, energy constrains, lack of centralized infrastructure and link capacity make load balancing over these networks a challenging objective. Also a major concern in MANET is energy conservation due to the limited lifetime of mobile devices. Energy is a precious resource in MANET. For many multi-hop scenarios, nodes are battery-operated, thus requiring efficient energy management to ensure connectivity across the network. Findings: In MANET, balancing the load can evenly distribute the traffic over the network and to prevent early expiration of overloaded nodes. To achieve this, we combine load balancing and energy aware routing technique and named as Path Efficient and Energy Aware Ad Hoc Multipath Distance Vector (PE-EA-AOMDV) routing protocol. Improvements: The proposed scheme is simulated and results show that there are significant improvements in the proposed scheme compared to AOMDV, PEAOMDV and EA-AOMDV with respect to packet loss, normalized routing overhead, packet delivery fraction, throughput and routing overhead.
