.NET Project On A QoS-Oriented Distributed Routing Protocol for Hybrid Wireless Networks

ABSTRACT:

As wireless communication gains popularity, critical research has been committed to supporting real-time transmission with stringent Quality of Service (QoS) necessities for wireless applications. In the same time, a wireless hybrid network that coordinates a mobile wireless ad hoc network (MANET) and a wireless infrastructure network have been proven to be a better alternative for the next generation wireless network. By directly adopting resource reservation-based QoS routing for MANETs, hybrids networks inherit invalid reservation and race condition issues in MANETs. How to guarantee the QoS in hybrid networks remains an open problem.

In this project, we propose a QoS-Oriented Distributed routing protocol (QOD) to improve the QoS support capability of hybrid networks. Taking advantage fewer transmission hops and anycast transmission highlights of the hybrid networks, QOD transforms the packet routing issue to a resource planning issue. QOD consolidates five algorithms: ) a QoS-guaranteed neighbor selection algorithm to meet the transmission delay requirement, 2) a distributed packet scheduling algorithm to further reduce transmission delay, 3) a mobility-based segment resizing algorithm that adaptively adjusts segment size according to node mobility in order to reduce transmission time, 4) a traffic redundant elimination algorithm to increase the transmission throughput, and 5) a data redundancy elimination-based transmission algorithm to eliminate the redundant data to further improve the transmission QoS. Analytical and simulation results based on the random way-point model and the real human mobility model show that QOD can provide high QoS performance in terms of overhead, transmission delay, mobility-resilience, and scalability.

EXISTING SYSTEM:

Reservation-based QoS routing protocols have been proposed for MANETs that make routes framed by nodes and links that hold their resources to satisfy QoS necessities. In spite of the fact that these protocols can increase the QoS of the MANETs to a specific extent.

PROPOSED SYSTEM:

In this project, we propose a QoS-Oriented Distributed routing protocol (QOD) to improve the QoS bolster the ability of crossover systems. Taking advantage fewer transmission hops and any cast transmission highlights of the hybrid networks, QOD transforms the packet routing issue to a resource scheduling issue.
