Enhanced Robust Ad-hoc Sensor Routing (RASeR) Protocol with Trust Authentication Scheme for Wireless Sensor Networks

Abstract: Robust Ad-hoc Sensor Routing (RASeR) protocol is designed to be a reliable solution, even with the high frequency topology changes of a mobile network. It uses a simple hop-count gradient to allow sensor nodes to blindly forward data towards a single sink. A key issue with this type of routing is in keeping the gradient metric up to date, for this reason RASeR uses a design that combines a global time division multiple access (GTDMA) medium access control (MAC) scheme with the routing protocol. In proposed work, the communication in Mobile Ad-Hoc Network (MANET) is based on mutual trust between the participating nodes. Due to features of open medium, dynamic changing topology, lack of centralized monitoring and management, MANETs are vulnerable to various security attacks. Hence, finding a secure and trustworthy end-to-end path in MANET is a real challenge. The proposed analysis shows significant improvement in packet delivery ratio of AODV in the presence of attacks, with marginal rise in control traffic overhead. The forwarding technique used inherently takes advantage of route diversity, which is designed to utilize multiple paths simultaneously, such that if one route fails there is another still active to deliver the packet. This makes the protocol very dependable in terms of packet delivery and very robust to link failure.
