Reliable Opportunistic Adaptive Routing In Wireless Sensor Networks in Contradict To Denial of Service

Wireless Sensor Networks sends data from sender to base station using number of sensors. However, the multi hop routing of WSNs often becomes the target of malicious attacks. Traditional cryptographic-based security mechanism have proved to be ineffective against several hard-to-detect insider attacks such as wormhole attack, sinkhole attack, sybil attack, selective forwarding attack, etc. These attacks further produce severe impacts on replaying of routing information and also aggravate identity deception. Present routing algorithms and protocols could not solve these severe problems. For such circumstances, TARF can be used to provide a trustworthiness and energy efficient route without any known geographic information or tight time synchronization. Most importantly, TARF proves effective against those harmful attacks developed out of identity deception; the resilience of TARF is verified through extensive evaluation with both simulation and empirical experiments on large-scale WSNs under various scenarios including mobile and networks. Other WSNs related problem is Denial of Service which is caused by many popular attacks. DoS attacks are complex and serious problem affecting not only a victim but the victim’s legitimate clients as well. TARF provides protection against above mentioned attacks but fails to ensure protection against DoS. In our proposed system, we make an endeavour to introduce a mechanism to tackle DoS attacks on the wireless sensor network which would further strengthen its security in all aspects.
