Wireless Sensor Networks (WSNs) have inherent and unique characteristics rather than traditional networks. They have many different constraints, such as computational power, storage capacity, energy supply and etc. Energy aware routing protocol is very important in WSN, but routing protocol which only considers energy has not efficient performance. Therefore considering other parameters beside energy...
Recent technological advances in miniaturization and wireless communication have made Wireless Sensor Networks an active research field. The increasing number of multimedia and real-time applications for Wireless Sensor Networks has led to a growing interest in Quality of Service for this category of networks. In this paper, we propose a QoS-geographic and energy aware routing protocol for Wireless...
SPEED routing algorithm is a service quality based algorithm in which data aggregation dose not happen. In this article, data aggregation has been added to the conventional technique in SPEED algorithm. The idea involves virtual configuration of sensors and specification of an individual ID to the created data by the sensors in each region, then data aggregation in relay node is done by this ID, resulting...
In wireless sensor networks (WSNs), a challenging problem is how to advance network QoS. Energy-efficiency, network communication traffic and failure-tolerance, these important factors of QoS are closely related with the applied performance of WSNs. Hence a QoS-aware routing protocol called directed alternative spanning tree (DAST) is proposed to balance the above three factors of QoS. A directed...
