Networks are affected by various types of attacks
such as sinkhole attacks, wormhole attacks and Sybil attacks.
Cryptographic techniques for developing routing protocols do not
address these problems. To secure WSNs against multihop
routing, a framework is designed for dynamic WSNs. The
framework demonstrates steady improvement in network
performance by providing trust worthy and energy efficient
route. The effectiveness is verified through extensive evaluation
with simulation and empirical experiments on large scale WSNs.

framework
A robust trust aware routing framework for WSNs secures
multihop routing in dynamic WSNs against harmful
attackers by exploiting the replay of routing information.
Framework focuses on trustworthiness and energy
efficiency, which are vital to the survival of a WSN in a
hostile environment. With the idea of trust management,
framework enables a node to keep track of the
trustworthiness of its neighbors and thus to select a
reliable route. This prospective has a noticeable impact on
WSN for their strong energy efficiency, robustness and
self configuration requirements. Framework effectively
protects WSNs from severe attacks through replaying routing information; it requires neither tight time
synchronization nor known geographic information.
