An Advanced Dynamic Optimized Routing (DOR) Protocol Based on Clustering for WSN to Enhance Energy Efficiency

P.Ponsekar, Dr.M.Sengaliappan


A "Wireless Sensor Network (WSN)" was a self-configurable group of spatially dispersed and dedicated "Sensor Nodes (SNs)", which can sense, process, and communicate among themselves using radio signals. The data sensed from various SNs are routed to the distant sink node will reduce the energy level of the intermediate SNs, which constitutes the primary issue in the WSN that degrades the network’s performance significantly. Cluster-based routing is one of the approaches in this area for efficient usage of energy in WSNs. In WSNs the routing path needs to be reliable and persistent, especially in multi-hop communication. The SNs along the selected routing path exhaust their energy rapidly due to the frequent exchange of messages. In these circumstances, when the discovered routing path and the fixed "Cluster Head (CH)" is disconnected due to energy depletion, the cluster-based routing mechanism must reconstruct the routing path. This reconstruction might lead to additional energy consumption for SNs, which reduces the energy level of the SNs. Hence, an optimized routing mechanism is required for efficient and reliable communication in the WSN. A novel "DynamicOptimizedRouting (DOR)" protocol has been proposed in this paper for WSN by dynamically selecting the "Cluster Heads (CHs)" in a rotation period based on their "Residual Energy (RE)" from the "Cluster Region (CR)". Through the proposed DOR protocol the SNs sense the information from various context and transmits the information to the sink node using the temporary CHs with higher energy dynamically. This efficiently minimizes the number of explicit control packets and also reconstructs the routing path in the path damage scenario. Thus it maximizes the "Packet Delivery Ratio (PDR)" and the "Energy Efficiency (EE)" of the network by selecting the efficient path from the source SN to the sink node. We compare and analyze the performance of the proposed DOR protocol with the existing E-BEENISH protocol with network parameters such as "Energy-Efficiency","Packet-Delivery-Ratio", "Throughput", and "RoutingOverhead" in the WSN
