Congestion and Energy Aware (CEAODV) Routing Protocol for Mobile Ad Hoc Network in Disastrous Situation

It is pain full and difficult for government and Non-Government Organizations to handle critical situations in dense and populous areas where high rising buildings are collapsed suddenly due to natural disaster. The telecommunication services were partially or fully damaged and did not responded accordingly. To reduce the losses of public property and save the lives of disaster victims in the disaster stricken areas, mobile ad hoc network is essential for launching rescue and relief operations. The CEAODV routing protocol has been designed and implemented in NS2.35 network simulator software. CEADOV routing protocol discover routes in such critical situations and share some related emergency information. The node mobility and network congestion badly degrade the performance of the mobile ad hoc network. This study has been designed the CEAODV routing protocol, evaluated its performance and compared with existing AODV reactive routing protocols in terms of Packet Delivery Ratio, End-to-End Delay and Energy Consumption. In the proposed scenarios CEAODV maximizes Packet Delivery Ratio in Traffic Load averagely by 34% and Node Mobility Speed by 17.12%. Network reduces End-to-End Delay in Traffic Load averagely by 23.24% and Node Mobility Speed by 22.38%. The network Energy Consumption reduces in Traffic Load averagely by 14.07% and Node Mobility Speed by 17.82%. The proposed routing protocol improves overall performance of the entire network, reduces packet losses, reduces network congestion and maximizes packet delivery ratio of the network.
