History trust routing algorithm to improve efficiency and security in wireless sensor network

Wireless sensor network (WSN) considered as one of the important technology in our days. Low-cost, low-power and multifunction based on these characteristics WSN become more and more apply in many areas. However, one of the major challenges in WSN is the security. Indeed, the usual method of security cannot be applied in WSN because the technological limit of the different components. In this context, we propose a new method to establish a secure route between the source node and the Sink node. Particularly, our method based on routing trust history table (RTH) and trust path routing algorithm (TPR). Therefore, our method offers a high level of security for the routing path with efficiency and stability in the network.
