Centralized and Distributed Energy Efficient Routing Techniques in Wireless Sensor Networks: A Survey
Recent technology improvements that have been developed in small size nodes, low-cost, battery power devices, which are capable of local processing and efficient wireless communication. Such nodes are called as sensor nodes. These sensor nodes are efficient in computing in various applications, such as office buildings, industrial plants, and reading temperature of a particular region. Each sensor will be having a limited lifetime and hence the processing of data may loss some sensed data due to battery power, collision while communicating between the nodes and having multipath links to reach the destination.
