For sensing environment, wireless sensor networks consist of huge number of low-cost, low-power and small nodes which have restriction on memory, power and computation resources. These nodes are sometime deployed in unfriendly environment where they can be tempered or physically not accessible. Topology of wireless sensor network remain changing as nodes can be added and deleted from network at any time and it is biggest challenge in developing routing algorithm for wireless sensor network. In this paper, the authors have presented some of routing protocols and algorithms available for wireless sensor network and shown comparison of them.
