Abstract
Due to the unmanned nature of Wireless Sensor Networks, security becomes a key criterion when it comes to networks dealing with confidential data. Compromised node, Denial of Service (DoS) [1] attacks and Black-Holes/Sink-Holes [2] are the three key types of attacks in Sensor Networks. Classic routing algorithms use deterministic multipath routing schemes, where a predefined path exits between any two nodes. Once if the adversary acquires the routing algorithm it is possible to compute the route, making all information sent over these routes vulnerable to its attacks. Our approach involves selecting intermediary nodes for each packet rather than sending the packets directly to the destination node. This way, the user initially disperses all the packets that are to be transmitted using a modified form of Backpressure algorithm [4] and then directs them to the destination node using SENCAST [5]. By following this method, most of the packets that are sent through a network have the probability of escaping black holes. Simulations show that our approach is much more effective in terms of security when compared to their deterministic counterparts.
