Abstract-Currently in the literature, there are quite a number of multi-hop routing algorithms, some of which are subject to normalization.Routing protocols based on clustering provide an efficient method for extending the lifetime of a wireless sensor network. Except that much of the research focuses less on communication between the Cluster-Head (CH), the nodes and the base station, and gives even less importance to the influence of the type of communication on the Life of the network.The aim of this article is to make a comparative study between some routing algorithms. Since they are not based on analytical models, the exact evaluation of some aspects of these protocols is very difficult. This is the reason why we make simulations.To study their performance. Our simulation is done under NS2 (Network Simulator 2). It allowed to obtain a classification of the different routing algorithms studied according to one of the metrics such as the loss of message, and the lifetime of a network.
