TCP, the facto standard used in today's Internet, has been found to perform poorly in Mobile Ad Hoc Networks (MANETs). This is exacerbated by contention with increasing UDP-based high priority multimedia traffic and the class differentiation introduced in current QoS protocols, which results into TCP starvation and increased spurious timeouts. In this paper, we propose a cross-layer TCP enhancement...
In the mobile ad hoc networks (MANET), all hosts are roaming. The network that interconnects these mobile hosts is a wireless one with a frequently changing topology, and there are no fixed infrastructures. It is more challenging to develop resource management methods for mobile ad hoc networks compared with infrastructured networks. Many previously proposed mechanisms are not well suited for MANETs,...
This paper we discuss the architecture of a QoS based mobile ad-hoc network MANET using RSVP over multiprotocol label switch (MPLS). Classical IP routing provides only a "best effort" service, which makes routing simple, however no quality of service (QoS) will be provided to applications such as streaming voice and video. For the purpose of scalability, where many connections are to be...
Mobile ad hoc network is an autonomous system of mobile nodes characterized by wireless links. A major challenge lies in adapting multicast communication to environments where mobility is unlimited and failures are frequent. The multicasting concept deals with one to many data dissemination, many multicast routing algorithm have been proposed like ODMRP, CAMP, NTPMR and so on. In this paper we design...
