In wireless network data transfer is a secure one, because the intruders may use duplicate IP addresses to hack the confidential data. Hop-by-hop authentication is necessary for secured communication. Hop-by-hop authentication is obtained by MAC address lookup table. The main goal of this work to protect contents of sensor data from attackers, including external intruders and unauthorized network users. For this purpose, we need to define and enforce a flexible access policy for each individual user based on the user’s role in the system. In particular, the access policy should be able to define a unique set of data that the user is authorized to access, and must be enforced via a cryptographic method since sensor nodes are vulnerable to strong attacks.Keywords

This paper presents methods to improve lifetime of the wireless sensor networks (WSN). Wireless sensor networks consisting of several thousands of sensor nodes and few sink nodes. There are three different methods proposed and one method used to increase the lifetime of the WSN. The methods are – rescheduling the network, mutli-hop transmission and deleting the weak node from the network. A multi-channel system is used to create a cellular structure by assigning one frequency channel per cluster. We have used simulator to evaluate sensors energy level in various rounds. The results are studied and analyzed.
