-------------------------------------------------------------------ABSTRACT-------------------------------------------------------------Mobile Ad Hoc Network (MANET) is an autonomous mobile nodes forming network in an infrastructure less environment and has dynamic topology. MANET reactive protocols always not have low control overhead. The control overhead for reactive protocols is more sensit...

Agent based micro-mobility protocols such as Hierarchical Mobile IPv6 deploy special IPv6 nodes called Mobility Agents that act as an anchor point between the Mobile Node and the Home Agent providing localized mobility support. The location and the number of MAs deployed within the network can affect the performance of the protocol. This paper deals with the problem of Mobility Agent (MA) locat...

In this study we created a new routing fabric for reducing power and delay. The power consumed in a FPGA core consists of both static and dynamic components. Static power contributes only 10% of the total power consumed in a FPGA. On the other hand, dynamic power contributes over 90% of the total power consumed and it is the main source for their power inefficiency. By reducing net length and/o...

Most of the previous efforts regarding multicast routing in MANETs, have been devoted to the provision of low-control overhead protocols, being able to maximize the packet delivery ratio. In multicast routing, the non-optimality of the forwarding structure can also lead to transmission of additional data packets (compared to the minimum required). We call those additional data packets data-over...

MANET packet transmission is unsecure since packets are damaged because of poor connection between nodes available in network environment. Link establishment is important for data broadcasting among sender to target node. Radio range makes the link, poor radio range cause imperfect link. Traffic occurred for communication performed in routing path. Since it contains lot of information about pac...

Received Oct 23, 2017 Revised Dec 29, 2017 Accepted Jan 20, 2018 This paper aims to improve the performance of the traditional routing protocol for MANET such as DSR and AODV in terms of delay and overhead. The proposed routing scheme is called as Extremely Vibrant Routing (EVR) which adopts with the highly dynamic environment of MANET. The link residual life is estimated to reduce the link fai...

The specific features of mobile ad hoc networks (MANETs) impose new requirements for routing protocols. The aim of this paper is to present an approach that enhances routing performance by integrating ad hoc related characteristics. We propose a loop-free adaptive path energy conserving scheme which attempts to minimize both routing and storage overhead in order to efficiently provide robustnes...

A Quality of Service (QoS) routing protocol for the Differentiated Services framework is being developed at the University of Coimbra (UC-QoSR). The main contribution of this paper is the evaluation of the protocol in wide area networks concerning traffic performance and protocol overhead. Many interesting QoS routing proposals have been proposed. However their evaluation has been conducted in ...

Varying the route caching scheme can significantly change network performance for on-demand routing protocols in mobile ad hoc networks (MANETs). Initial route caching schemes retain paths or links until they are shown to be broken. However, stale routing information can degrade network performance with latency and extra routing overhead. Therefore, more recent caching schemes delete links at s...

In mobile ad hoc networks the nodes will be in a mobile state so there may be a frequent link breakages which leads to frequent path failures and route discoveries. Sending periodical message causes overhead. Reactive Routing protocol causes less overhead when compared to Proactive routing protocol. In the existing system they used neighbor coverage based probabilistic rebroadcast protocol(NCPR...
