CASER tool is used to increase the life time of the networks. Caser tools use two parameters (i) energy balance control and (ii) probabilistic-based random walking. The EBC uses for energy consumption and the other one used for security. We propose non uniform technology in energy balanced consumption. In uniform technology the data’s can’t be send it for longer nodes to overcome this problem the non-uniform technology is proposed. Then we compared the Sleep awake protocol which is used to send the packet in energy efficient way Keywords: Sensor networks, CASER, EBC, Protocols, Security 1. INTRODUCTION A computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices pass data to each other along data connections. Data is transferred in the form of packets. The connections (network links) between nodes are established using either cable media or wireless media. The best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices are said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. The recent technological advances make wireless sensor networks (WSNs) technically and economically feasible to be widely used in both military and civilian applications, such as monitoring of ambient conditions related to the environment, precious species and critical infrastructures. A key feature of such networks is that each network consists of a large number of un-tethered and unattended sensor nodes. These nodes often have very limited and non-replenishable energy resources, which makes energy an important design issue for these networks.
