Wireless sensor network is a collection of small sensor nodes with ability to sense, compute and transmit data that are deployed to observe a physical environment. Data dissemination and gathering protocols design for wireless sensor network is crucial challenge since these protocols are should be easy, energy efficient and robust to deal with such a large number of nodes. LEACH is a hierarchical protocol in which most of the nodes transmit data to cluster heads, and the cluster heads aggregates and compresses the data and forward it to the base station (sink). PEGASIS (Power-Efficient Gathering in Sensor Information Systems), a near optimal chain based protocol that is an improvement over LEACH.
