Due to the special characteristics of wireless sensor networks, traditional MAC approaches are not suitable for them. So designing MAC protocol for WSNs in a specific manner is critical to meet their intrinsic constraints. In this paper, we proposed an energy efficient MAC protocol which reduce energy consumption due to idle listening and control packet overhead. It is called W-MAC. W-MAC protocol...
Wireless Sensor Network has been widely used in many important fields. However, the energy problem has been becoming a challenge in practical applications for WSN. Medium Access Control has a significant effect on the energy consumption. In this paper, we described an energy-efficient SMAC protocol, which is a well-known MAC protocol for WSN. Then, we introduced TMAC protocol, DMAC protocol and SSMAC...
In the wireless sensor networks (WSNs), Synchronous approaches share the schedule information that specifies the cycle of active and sleep period by the control packets. On the other hand, asynchronous approaches do not exchange the synchronization information to send or receive data. Instead, they employ preamble sampling to do that. In this paper, we compare and analyze synchronous and asynchronous...
The design of medium access control (MAC) in wireless sensor networks (WSNs) poses several key factors such as energy conservation, bandwidth utilization, throughput, etc. This paper proposes a new MAC protocol referred to as DEE-MAC which reduces energy consumption by making the idle nodes sleep to reduce idle listening using synchronization at cluster heads. Each cluster is dynamically formed as...
