A wireless sensor network is a group of large number of nodes which are randomly deployed in a specific area. This deployment of nodes is in form of number of clusters. The main purpose of these nodes is to sense the surrounding condition like temperature, humidity etc. and send it to the central processing unit through the intermediate nodes following some routing protocol. The main concern here is the energy consumption by these nodes during the data communication as these nodes are equipped with non-rechargeable batteries. Currently much of the research is going on to design such routing protocol which can make the network energy efficient or to increase the lifetime of network. This paper provides a comparative review of clusterization and routing algorithms provided in the different literatures for wireless sensor network. Comparison was carried out on the basis of node density, types of nodes connectivity, network coverage area and cluster head selection probability.
