Co-Operation in Wireless Sensor Networks for Smart Cities

Abstract

Sensor deployment in smart city scenarios introduce multiple challenges such as node capacity management, node management, and communication latency. As the size of the sensor network increases, there must be novel or multiple strategies to improve efficiency of the network. The goal of this chapter is to explore and highlight research strategies in this area. There has been work in this area, but there are multiple emerging challenges in this area due to explosion in number of sensor nodes and the functionalities embedded in these nodes in smart city and healthcare applications. Node co-operation or node collaboration is a method to localize large-scale sensor networks. This method has been explored in cellular networks to improve spectrum utilization. There is much interest and scope in node co-operation/node collaboration in sensor networks as collaboration can be exploited to control the topology, minimize communication overhead, and conserve energy at the node.
