1. A QoS-Oriented Distributed Routing Protocol for Hybrid Wireless Networks
A QoS-Oriented Distributed Routing Protocol for Hybrid Wireless Networks
ABSTRACT
As wireless communication gains popularity, significant research has been devoted to supporting
real-time transmission with stringent Quality of Service (QoS) requirements for wireless
applications. At the same time, a wireless hybrid network that integrates a mobile wireless ad
hoc network (MANET) and a wireless infrastructure network has been proven to be a better
alternative for the next generation wireless networks. By directly adopting resource reservation-based
QoS routing for MANETs, hybrids networks inherit invalid reservation and race condition
problems in MANETs. How to guarantee the QoS in hybrid networks remains an open problem.
In this paper, we propose a QoS-Oriented Distributed routing protocol (QOD) to enhance the
QoS support capability of hybrid networks. Taking advantage of fewer transmission hops and
anycast transmission features of the hybrid networks, QOD transforms the packet routing
problem to a resource scheduling problem. QOD incorporates five algorithms: 1) 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,
Reservation-based QoS routing protocols have been proposed for MANETs that create routes
formed by nodes and links that reserve their resources to fulfill QoS requirements. Although
these protocols can increase the QoS of the MANETs to a certain extent.

2. A QoS-Oriented Distributed Routing Protocol for Hybrid Wireless Networks
DISADVANTAGES OF EXISTING SYSTEM:
 Cannot provide QoS-guaranteed services.
 Suffer from invalid reservation and race condition problems .
 Invalid reservation problem means that the reserved resources become useless and
Race condition problem means a double allocation of the same resource to two
different QoS paths.
 In this paper, we propose a QoS-Oriented Distributed routing protocol (QOD) to enhance
the QoS support capability of hybrid networks.
 Taking advantage of fewer transmission hops and any cast transmission features of the
hybrid networks, QOD transforms the packet routing problem to a resource scheduling
problem.
ADVANTAGES OF PROPOSED SYSTEM:
 QOD can provide high QoS performance in terms of overhead, transmission delay,
mobility-resilience, and scalability.
