—The migration to wireless network from wired network has been a global trend in the past few decades. The mobility and scalability brought by wireless network made it possible in many applications. Among all the contemporary wireless networks , Mobile Ad hoc NETwork (MANET) is one of the most important and unique applications. On the contrary to(More)
Mobile Ad-hoc NETworks (MANET) are infrastructureless networks where self-configuring mobile nodes are connected by wireless links. Because of its decentralized operation, these nodes rely on each other to store and forward packets. Video transmission over MANETs is more challenging than over conventional wireless networks due to rapid topology changes and(More)
A Mobile Ad-hoc NETwork (MANET) is an infrastructureless network consisting of self-configuring mobile nodes connected by wireless links. Nodes rely on each other to store and forward packets. Most of the proposed MANET protocols assume cooperative and friendly network context, and do not address security issues. Furthermore, MANETs are highly vulnerable(More)
— Due to the many benefits provided by both the third-generation (3G) mobile networks and the IEEE 802.11 wireless local area networks (WLANs), it is desirable to integrate both types of networks. While studies specifying generic integration architectures are abundant, there are little or no studies that are dedicated for applications performance over such(More)
A wireless mobile Ad hoc network (MANET) is a collection of wireless mobile hosts forming nodes that are arbitrarily and randomly changing their locations and communicating without the aid of any centralized administration or standard support services. Ad hoc cluster-based routing protocols establish a dynamic wireless mobile infrastructure to mimic the(More)
Many applications of Wireless Sensor Networks (WSNs) require accurate time synchronization for data consistency and coordination. While the existing protocols for time synchronization provide sufficient accuracy, they consume high energy and poorly synchronize the distant nodes. We propose a Recursive Time Synchronization Protocol (RTSP) which provides(More)
Packet reservation multiple access (PRMA) can be considered as a merge of slotted ALOHA protocol and time division multiple access (TDMA) protocol. Independent terminals transmit packets to base station by contending to access an available time slots. A terminal that succeeds in reserving a certain time slot keeps on this reservation for transmitting its(More)
Increasing speed of hardware device and versatile functionalities of small equipments e.g. laptop, PDA etc. are introducing various voice oriented applications with mobility. Like other computer networks, in Mobile Ad-hoc Network (MANET) voice transmission is very much demanding and necessary. In this research paper we have a feasibility analysis of voice(More)
