Rapid penetration of small customized wireless devices and enormous growth of wireless communication technologies has already set the stage for large-scale deployment of wireless sensor networks. Offering precise quality of service (QoS) for multimedia transmission over sensor networks has not received significant attention. However offering some better QoS for wireless multimedia over sensor networks...
This paper presents an original performance analysis of the contention-based channel reservation schemes, namely UNI MAC in wireless communication systems. Here we mathematically derive the expression of the performance in term of success rate where the impact of misbehaving users is also taken into account. Validated with the simulation results, our numerical results show that the overall performance...
Recently, an energy aware data centric routing protocol (EAD), was proposed and its performance outperforms other existing routing protocols such as LEACH. However, EAD has an inherited problem that only closed nodes to the sink will be chosen as gateways which eventually leads into isolating the rest of the network's nodes even though they still have enough power to communicate with the sink. In...
