ABSTRACT:
Extending the lifetime of the wireless sensor networks (WSNs), where
recharging sensors is not always possible, has been a major concern for
researchers for the past decade. In this paper, we study the cooperation
between nodes in wireless sensor networks in forwarding packets to others, and
we propose a new collaboration technique which stimulates intermediate nodes to
forward packets toward their destination. Some nodes show selfish behavior by
denying the forwarding packets to other nodes in commercial networks in an
effort to preserve their own energy. This paper applies a technique which is
used to prolong the network lifetime, based on a node’s energy and trust value,
and additionally incorporates fuzzy logic, which stimulates nodes to forward
packets by rewarding cooperation. According to simulation results, the proposed
approach surpasses the Nuglets (virtual currency) approach and the Reputation approach in network energy and thus prolongs the network lifetime. Additionally,
our proposed approach demonstrates better results in the number of dropped
packets, PDR and forwarded packets to neighboring nodes.
