QoS-Based Routing Protocol with Load Balancing for Wireless Multimedia Sensor Networks Using Genetic Algorithm
نویسنده
چکیده
Wireless sensor nodes have been provided with some parts in order to receive audio and video like camera and microphone which were called wireless multimedia sensor networks (WMSN). In this paper, we proposed a new QoS-based routing protocol for WMSN. This protocol is routed according to quality of service (QoS) requirements for each data packet. With each packet, protocol tries to perform routing according to existing QoS-based criteria in data and by considering energy efficiency, delay and reliability. This protocol is modeled based on geographical information. We evaluate the path's quality of service based on queuing theory and genetic algorithm (QGA) and assign a weight for each one of the quality of services of delay, consumed energy and reliability and select the best path. This mechanism first determines the data types according to reliability, residual energy and delay in sensor nodes. Simulation results show that this protocol provides better quality of services with QoS based requirements for several types of traffic and increases the lifetime of network compared with previous protocols due to load balancing in network.
