An Efficient method for the advancement of performance of wireless sensor network

In this paper, the main focus or emphasis is given on the upgrdation of the performance of the wireless sensor network or it may be a general wireless network .The main issue is towards the monitoring of the delay issue & network lifetime issue.wireless sensor network also suffer from the different problems or vulnerabilities. WSN suffer from attacks due to which there is an impact on the performance of the wireless sensor network.our main aim in this paper is towards the advancement in the performance of the wireless network.Also towards the maximization of network lifetime & minimization of delay term. Wireless sensor networks consists of many sensing nodes that captures the changes in the environment enclose data in data packets and gives these packets to sink node present in the network. A WSN consists of a number of sensors spread across a geographical area. Each sensor has wireless communication capability and sufficient intelligence for signal processing and networking of the data. The network lifetime is usually defined as the time until the first node fails because of energy depletion. So sleep-wake scheduling is effective mechanism to increase network lifetime. Sleep-wake scheduling is efficient to increase network lifetime but it could result insubstantial delays because a transmitting node needs to wait for its next-hop relay node to wake up. Anycast forwarding schemes to forward the data packet to next hop node which minimizes the expected packet-delivery delays from the sensor nodes to the sink node.CMAC avoid the synchronization while supporting the latency.
