Low-energy Adaptive Clustering Hierarchy protocol and optimal number of cluster head algorithm in a randomized wireless sensor network deployment

Abstract:

Wireless sensor networks systems have a lot of problems like security, energy consumption, heterogeneity and other disadvantages that need be solved. In this paper we look the best energy model protocol choice for a random topology and deployment in a sensor network, considering cluster establishment phase and stable data transmission, regarding different types of energy consumption, distances, and interference. We choose two protocols to submit in a simulation using MATLAB, the first one Low-Energy Adaptive Clustering Hierarchy protocol (LEACH) a protocol that use randomized rotation of cluster heads in the network and this protocol consider all the parameters that will be tested. The second protocol will be the Optimal number of cluster heads (ONCH) algorithm according to this algorithm the best way to obtain safe energy in a better way is optimizing the number of clusters heads in the network considering the number of nodes, radio, different routing coefficients and energy consumption. We will see which of these alternatives are the better option is when we have a random wireless sensor network deployment.
