Advances in wireless communication as well as in sensor technology have enabled many Wireless Senor Network (WSN) applications. Unfortunately, operational challenges faced by WSNs still hinder their wide deployment. Therefore, researchers are still looking for reliable, real time, and energy efficient structures and routing protocols which can effectively disseminate information in WSNs as traditional techniques such as flooding have proved to be unproductive. In this paper we propose two routing protocols: non-opportunistic and opportunistic. The non-opportunistic protocol is highly adaptable, while the opportunistic protocol will save energy by selecting the next forwarding node dynamically based on prior knowledge of packet delivery to neighboring nodes. The performance of the proposed protocols is evaluated against the traditional protocols, such as Low-Energy Adaptive Clustering Hierarchy (LEACH) and Collection Tree protocols.
