Performance /efficiency enhancement of Dynamic Source Routing Protocol in Wireless Mesh Networks

A Wireless Mesh Network is a collection of wireless nodes that form a network connection. There are several routing protocols like TORA, HEAT, AODV and DSR etc. which have been designed for providing communication among all the nodes in the wireless network. DSR is a reactive routing protocol and comfortable for unlimited number of nodes. This paper presents the comparison performance of DSR protocol with E-DSR (enhanced-DSR) protocol. In the enhanced approach of DSR, we improve the performance of Packet Delivery Ratio and throughput of the Wireless Mesh Networks. In E-DSR the destination a node recognizes first route request message (RREQ), it produces Turn-Around route request (TA-RREQ) message and deluges it to neighbor nodes within transmission range. E-DSR decreases route fail variation messages and gets very good performance as compared to Dynamic Source Routing protocol (DSR). Keywords— WMNs, Packet Delivery Ratio, HEAT, E-DSR, RREQ (Route Request), RREP (Route Reply); Organization of the paperThe present paper has been organized into eight topics starting from the introduction of the Wireless Mesh Network and E-DSR. Topic second explains the literature review regarding Dynamic Source Routing. Topic third describes about the problem statement. Topic fourth tells us the overview of proposed enhanced-DSR (D-DSR), implementation work, working procedure of proposed enhanced-DSR algorithm, implementation code for E-DSR. Topic five depicts the experimental setup for simulation. Topic six describes about analyze the metrics based performance results for DSR and E-DSR. Topic seven describes the references. Topic eight concludes this paper. At last of this paper, there is description about the author.
