In energy constrained wireless sensor networks, it is very important to conserve energy and prolong active network lifetime while ensuring proper operations of the network. To extend the lifetime of a sensor network, one common approach is to dynamically schedule sensors¿ work/sleep cycles (or duty cycles). In our work we have considered cluster based(More)
With growing sophistication of computer worms, it is very important to detect and prevent the worms quickly and accurately at their early phase of infection. Traditional signature based IDS, though effective for known attacks but failed to handle the zero-day attack promptly. Recent works on polymorphic worms does not guarantee accurate signature in(More)
Wireless Sensor Network (WSN) is severely energy constrained. Selecting an energy efficient routing is very important for such network. In this paper, we present an approach for routing in wireless sensor network to minimize the energy consumption to increase active lifetime of the network. Our approach takes the minimum energy route for transmitting data(More)
