In this paper, we introduce a new medium access control (MAC) protocol for event-driven wireless sensor networks (WSN). Generally, there are three models of WSN: continuous, on-demand and event-driven. They have different characteristics and each requires a different design model. In the event-driven WSN, the sensors send data only when certain events(More)
In this paper, we propose OBMAC, an enhancement for medium access control (MAC) protocol based on the overhearing technique in wireless sensor networks (WSNs). In this type of networks, sensors are spatially correlated and they often sense and send the same information to the sink. Therefore, sensors waste energy in transmitting redundant data. Here, we(More)
In this paper, we present a new contention access method for scalable wireless sensor networks. In these networks, the traffic levels are often variants, particularly in monitoring applications. Sensors do not regularly have much data to send. However, when an event occurs, every sensor in a given area will send its alert to the access point simultaneously.(More)
In this paper, we present a low latency media access control scheme which we call LLMAC (Low Latency MAC) for event-driven wireless sensor networks (WSN). In this kind of WSN, sensors do not regularly send data to the sink. They send a burst data only when there is an event in the monitoring area. It takes time for this burst data to arrive to the sink.(More)
