Performance Analysis of WSN Routing Protocols with Effective Buffer Management Technique

Routing in WSN has dependably been a serious issue of concern mainly because of a few case studies which extend from unfriendly deployment conditions, network topology that change over and over, network failures, resource constraints at each sensor hub to issues in designing of routing protocols. Accordingly, the implementation of routing protocol is influenced by a few fundamental elements which must be thought of before any attempt at designed routing are implemented. Two major protocols used in WSN are Dynamic-Source Routing (DSR) and Destination Sequenced Distance Vector Routing (DSDV). DSR protocol is mainly source based routing protocol and implemented to limit the bandwidth utilized by packets in WSN by avoiding the regular messages transmitted to update table in table-driven approach. The proposed system is Multilayer Buffer Management DSR (MBMDSR) where multilayer buffer management mechanism is implemented in existing DSR protocol and a considerable increase in performance was noted.
