Heterogeneous Wireless Sensor Networks � Redundancy Management of Multipath Routing

Abstract
Un reliable and malicious nodes create a lot of problems in wireless sensor networks. To address the energy consumption and QoS gain in reliability, delay and security with the goal to maximize the lifetime of a clustered Heterogeneous Wireless Sensor Networks while satisfying application QoS requirements in the context of multipath routing. The proposed research is a highly scalable cluster-based hierarchical trust management protocol for wireless sensor networks (WSNs) to effectively deal with selfish or malicious nodes. The proposed work consider multidimensional trust attributes derived from communication and social networks to evaluate the overall trust of a sensor node. The protocol relies on a new multipath constructions paradigm that is defined specifically for heterogeneous WSN. The approach leverages a reasonable increase in the network lifetime and a higher resilience and fault tolerance.
