Investigation on AODV and DSR Protocols for The Improvement of QoS in Wireless Network: A Survey

Wireless technology is one of the major communication technology based on sensor base communication channel, it is one of the most demanded technology at all, nowadays user are very much comfortable to work with Wireless Communication environment, quality of service factors always takes an important value among the remaining things in which it uses the transfer energy level of every node that support communication boosting. In this case not only the energy scarcity, but also the quality of service (QoS) guarantees need to be taken into account. Other major area will be consider under WSNs that multiple category of application in WSNs affect major challenges over the quality of services provided my WSNs .In order to reduce the issue of poor communication along with the measurement of quality of service work it is very compulsory to go through the traditional major drawback find in the previously proposed algorithm which provides the WSNs services during dynamic walk and circumstances to get implement the QoS constrains , Since wireless technology are growing through major demand in today’s environment peoples are like portable communication system that can be done only by the way of wireless communication system but it is not necessary to find the QoS in this aspect some time user find wireless media as best friend of successful and qualitative communication but sometimes they suffer with major performance level issues like bandwidth, delay and data loss issues that directly or indirectly will cause various problems related with the performance issues and quality measurement parameters. In order to rectify the solution of various problem related to the WSNs different algorithm and protocols has been proposed time to time to improve communication services provided by WSNs, but the in this paper we try to focus on the quality of services issues with WSN so that in this paper author concentrate the quality of service specification covered through different traditional algorithm like AODV and DSR so that one can manage and develop new algorithm that not only provide the best communication services but also gives the high performance during heavy load with delay and throughput measurement.
