Secure Wireless Ad Hoc Sensor Networks

Our proposed new design PLGPn is suggested, which presents a various mechanisms of resource depletion attacks. This mitigates the various types of attacks by improving an already existing protocol called PLGPa. These are clean slate routing protocols capable of overcoming problems such as carousel attack, stretch attack, directional antenna attack and malicious discovery attack during topology discovery phase. Developing such mechanisms is used to avoid the looping among the nodes in the network by loop-free technique. This scheme provides defense for topology discovery and avoid looping concept in an efficient and robust manner even if there are a large number of active attackers in the network.
