An Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
متن کاملmac protocols in underwater wireless sensor networks: issues and simulations
underwater acoustic wireless sensor network (uawsn) use acoustic signalsto transmit data. acoustic signals in underwater environment have high bit errorrate, long propagation delay and limited bandwidth. another constraint in uwasnis energy. due to these constraints, design of energy and bandwidth efficient andpropagation delay aware mac protocol is a great challenge in uwasn.underwater sensor ...
متن کاملMAC protocols for wireless sensor networks
The paper presents a brief survey of the Medium Access Control (MAC) protocols for Wireless Sensor Networks (WSN). It describes pros and cons of some known solutions of the MAC protocols with emphasis on his energy efficiency. The main goal in WSN is prolonging the lifetime of the sensor node, that is usually battery powered and can thus be achieved by designing energy-efficient MAC protocols. ...
متن کاملTraffic Adaptive IEEE 802.15.4 MAC for Wireless Sensor Networks
IEEE 802.15.4 is a new standard uniquely designed for low rate wireless sensor networks(WSNs). It targets low data rate, low power consumption and low cost wireless networking, and offers device level wireless connectivity. In this paper, the general coordinated sleeping algorithm and the traffic-adaptive algorithm are combined in IEEE 802.15.4 MAC protocol to achieve high energy efficiency and...
متن کاملAn Adaptive Congestion Alleviating Protocol for Healthcare Applications in Wireless Body Sensor Networks: Learning Automata Approach
Wireless Body Sensor Networks (WBSNs) involve a convergence of biosensors, wireless communication and networks technologies. WBSN enables real-time healthcare services to users. Wireless sensors can be used to monitor patients’ physical conditions and transfer real time vital signs to the emergency center or individual doctors. Wireless networks are subject to more packet loss and congestion. T...
