Energy Saving in Heterogeneous Wireless Sensor Networks
Rashmi Jain, Manali M. Kshirsagar · 2013
In Wireless Sensor Network (WSN) the sensor nodes are very much sensitive to the energy consumption. The success of the wireless sensor network applications highly depends on the reliable communication among the sensor nodes. One of the major problems in WSN environments is the limitation of the physical resource that is energy resources. More energy is consumed in transmitting and receiving the data as compared to other processing done. Therefore we can use cluster based (Hierarchical) protocols in which the set of nodes are divided into different groups called clusters. For each cluster a cluster head is selected which is responsible for all the communication between the nodes in the cluster and the base station. Instead of homogeneous nodes some high energy nodes can be used to handle the clusters for a longer time. This paper uses concept of heterogeneous nodes to save some energy required for setup phase as in case of LEACH and alike protocols.
