A Fast Channel Assignment Scheme for Emergency Handling in Wireless Body Area Networks
Ubiquitous healthcare is a promising technology that has attracted significant attention in recent years; this has led to the realization of wireless body area networks (WBANs). For designing a robust WBAN system, the WBAN has to solve the drawbacks of wireless technology. Also, a WBAN has to support immediate, reliable data transmission for medical services during emergencies. Hence, this stud...
متن کاملChannel Assignment in Wireless Local Area Networks
The tremendous growth of wireless networks requires an efficient use of the scarce radio spectrum allocated to wireless communications. However, the main difficulty against an efficient use of radio spectrum is given by interferences, caused by unconstrained simultaneous transmissions, which result in damaged communications that need to be retransmitted leading to a higher cost of the service. ...
متن کاملRouting Hole Handling Techniques for Wireless Sensor Networks: A Review
A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...
متن کاملChannel Assignment Mechanism for Wireless Local Area Networks
Wireless Local Area Networks (WLANs) are subjected to interference because of their working in Unlicensed Spectrum. Coverage ranges of WLANs are 30 to 300m. Channel Assignment is one of the most important problems in the WLANs. In this paper we present a Survey on the Channel Assignment techniques in IEEE 802.11.After analyzing different methods a qualitative comparison has been carried out for...
متن کاملPerformance of Emergency Packet Handling Mechanism for Wireless Body Area Networks
To analyze and design an efficient transmission control mechanisms for handling critical and non-critical data in wireless body area network, we propose a packet handling mechanism in order to handle the emergency packet. In this paper the performance of emergency packet handling is compared with the existing technique and the simulation results show that the proposed protocol improves the thro...
