Using Dynamic Watchdog Optimization Technique for Secure Data Transfer in MANET

摘要

Energy efficiency and security plays a major role in MANET. To make this possible we are using Dynamic watchdog optimizing technique in two levels. First level of optimization is watchdog location optimizing. This level of optimizing technique use distance based probabilistic algorithm. This algorithm can find a set of watchdog nodes by considering those nodes locations in a probabilistic manner and to create shortest path between source node and destination node. Second level of optimization is uses Dynamic watchdog optimizing. This mechanism play role on as normal node acts as a watchdog node on responsible path. If packets successfully reach the destination a Watchdog node changes into normal node this mechanism called as Dynamic Watchdog Technique. Used for detect malicious node. It defines the number of task to be performed by watchdog node within a time window.
