Cooperative and secured Data Forwarding in AODV Routing Protocol
Sarath Menon · 2015
A Wireless sensor Network uses thousands of miniature devices that communicate among each other and sense data from the environment. The success of the communication in a WSN inherently lies in the routing protocol used by the architecture. This work is an extension to include security aspects and also to further increase the routing parameters. The Earlier work enabled reliable communication for Ad hoc On-demand Distance Vector Routing (AODV) in Wireless Sensor Networks. The problem was that These protocols are on-demand routing protocols and has the capability to only detect Link Failures. This would hamper the packet delivery ratio and increases the end-to-end delay. AODV Protocol when faced with a link failure condition had the source node reinitiate the route discovery phase by broadcasting Route Request Messages to its neighbours without considering the affected link. This work calls for an EAACK concept as an extension over the AODV-R3E protocol.. The Idea Of Enhanced Adaptive Acknowledgement improves the security aspects of the wireless sensor networks. Thus EAACK successfully augments the aforementioned AODV-R3E protocol, thereby still improving the packet delivery ratio and also achieving a significant reduction in end-to-end delay in the Wireless Sensor Network.
