Effect of Number of Active Nodes and Inter-node Distance on the Performance of Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are used to monitor different ambient conditions. These networks can be used for constant environment and habitat monitoring applications such as sensing of humidity, temperature, soil moisture and fire. All these applications have certain desired network performance and lifetime requirements. In this paper, we present our findings about variation in network performance and energy efficiency with varying number of active nodes and inter-node distance in WSNs. Change of network behavior with changing network conditions is studied through simulations carried out in ns2.34.
