Improving the Quality of Service in a Wireless Sensor Network Technologies- A Survey

A Wireless network is based on packet switching concept and is capable of handling a variety of applications. The challenge is to attain a better Quality of Service (QoS) for the like applications of real-time and non-real time in an interesting environment with varying bit rate, unpredicted channel lay off. The objective of QoS provision is to afford the opted services for the users while utilizing a particular application. It describes the concept of quality of services in wireless sensor networks (WSNs) in terms of small size sensor, low cost, low power, routing and capacity of wireless networks. By given that quality of service (QoS) support in wireless sensor networks is a sanatorium growing part of the research. Many control mechanism is necessary in order to guarantee the reliability, these are load capacity, bandwidth, flow control, an end to end transmission in the wireless communication networks. A cross-layer move towards is principally significant for any network using wireless technologies. Since the state of the physical medium can considerably vary over time. This survey paper presents various wireless technologies and its frameworks in QoS perspective.
