Abstract

AbstractMobile nodes in Wireless Sensor Network (WSN) are a group of mobile sensor nodes that form a volatile topology, nodes in WSN cooperate wireless to communicate from source to destination through multihop without any infrastructure. Mobility is the key characteristics of WSN which makes nodes break links frequently and change topology. Due to link failure, the network experiences a packet loss, which could lead to congestion and degrades the overall network’s quality of service (QoS) performance. It is a challenging issue for a routing protocol to adapt a proactive method for finding alternate routes with minimum delay and less energy consumption by considering congestion and link failure. To address this issue, this research paper proposes a dynamic shortest path routing by employing an Optimal Link-Sstate Routing (OLSR) scheme known as low latency optimal link-state routing (LLOLSR) to find the shortest alternate path whenever the link failure is detected between two nodes and also this scheme minimizes the path delay by integrating the congestion avoidance method and seeks to maximize the Packet Delivery Ratio (PDR).KeywordsWSNMobile nodesQuality of Service (QoS)Link quality
