    ABSTRACT: Providing desired QoS is one of the crucial issues in routing protocols design in wireless sensor networks. In this paper, a mechanism for routing in wireless sensor networks is presented using nonlinear optimization. Providing fairness in nodes energy consumption and increasing network lifetime are considered as the main parameters. Proposed routing protocol, which is called FORP (Fair, Optimized Routing Protocol), performs routing using nonlinear optimization. Furthermore, in order to improve proposed protocol efficiency, we will use fuzzy variables to consider environmental contention influences on the quality of data transmission in wireless connections. We can formulate network conditions better while fuzzy variables have been used in optimization solution. We will study proposed protocol efficiency using Opnet simulator. Simulation results confirm that FORP has achieved its goals.

    Chapter: An Efficient Energy Aware Routing Protocol for Real Time Traffics in Wireless Sensor Networks

    ABSTRACT: Energy aware routing is most challenging issue in wireless sensor networks. Current research on routing of sensor data mostly focused on protocols that are energy aware to maximize the lifetime of the network, scalable for large number of sensor nodes and tolerant to sensor damage and battery exhaustion. In this paper an efficient energy aware routing protocol was proposed. The proposed routing protocol has two major goals which are low power consumption and low end to end delay. We evaluated the performance of the proposed protocol under different scenarios. Simulation results confirmed that the proposed protocol has more efficient energy consumption in comparison with the traditional SPEED protocol. Furthermore, the proposed routing protocol can find the optimal path with a low end to end delay. We believe that, by using data aggregation techniques the higher performance will be achievable. Also using other cost functions for route selection makes the proposed protocol suitable for other applications.
