Development of Routing Protocols in Wireless Sensor Networks for Monitoring Applications

Abstract

In recent years, the rapid flourish of wireless sensor networks has led to concentrate the effort of researchers in different wireless networking concepts to implement smart, cheap, low power consumption, and wirelessly networked monitoring and control systems. Many applications in Wireless Sensor Networks (WSNs) require connectivity between sensors to route the gathered data to a base station node. This work presents a systematic performance study of three routing protocols namely: Ad hoc On Demand Distance Vector (AODV), Dynamic Source Routing (DSR), and Optimized Link State Routing (OLSR) protocols for WSNs. This is accomplished by proposing a simulation model that targeted the sensor networks with mobile sensor nodes and single sink as it is often seen in many monitoring applications such as military, agriculture, medical, transport, industry, etc to monitor the physical environments. The role of routing protocol under line strategy in monitoring applications is investigated. Time delay is considered a crucial issue in these applications.
