Title
An adaptive MAC protocol for ensuring throughput in wireless sensor networks
Abstract
In wireless sensor networks, centralized data collection at sink leads to funneling effect which causes traffic intensity. This phenomenon results in significant packet collision, congestion, and loss. Researcher has proposed a localized, sink-oriented funneling-MAC to mitigate this funneling effect. Actually, this MAC protocol contributes to reduce this problem. However, funneling-MAC is difficult to control when important traffic is outside of intensity region. In this paper, we propose the mechanism ensuring throughput and JSR when specific traffic such as emergency traffic is generated in the region using CSMA mechanism. For ensuring throughput and JSR(Job Success Rate), we allocate time slot to node that has a specific traffic. The results of simulation using NS2 show that the proposed algorithm clearly ensures throughput and JSR for specific traffic.
