Energy-efficient routing-based clustering approaches and sleep scheduling algorithm for network lifetime maximization in sensor network: A survey

Abstract

Along with number of problems associated with WSNs, one of the major issue we chose to study is their clustering topology and energy utilization techniques. Both these parameters are very much responsible in determining the life of nodes, quality of service, delay in data transmission, etc. So, it is very important to examine the cluster-based routing protocols and energy optimization protocols. The cluster routing is based on the selection of cluster head nodes for data transmission, and the parameters which are used for the making of an optimized network mainly depend on number of nodes, position of base station, and the network size. So, a well-settled cluster is tried to be designed with the study of various algorithms early proposed. And for energy optimization of network, we studied “sleep/wake-up” algorithm, which makes the nodes sleep during its ideal mode and wake it up when data transmission is to be done. With this sleep/wake-up algorithm important point to be kept an eye is the delay during this shifting between sleep and wake up or making sure that the selected path should not be engaged as well as it must be shortest path from base station. So, based on these two protocols, various papers are studied, and the comparative result of this protocol in various scenarios is carried out.
