Ad hoc networks are special networks that do not require an infrastructure. Nodes of such networks are usually mobile and wireless. Wireless nodes use a shared medium for communication, so they are able to communicate with many nodes directly provided they are within communication range of those nodes. An ad hoc network is a collection of wireless nodes dynamically forming a temporary network w...

As the network size increases the probability of congestion occurrence at nodes increases. This is because of the event driven nature of ad hoc networks that leads to unpredictable network load. As a result congestion may occur at the nodes which receive more data than that can be forwarded and cause packet losses. In this paper we propose a hybrid scheme that attempts to avoid packet loss due ...

In this paper, we have performed a comparative analysis on three different MANET protocols with respect to packet delivery ratio (PDR), throughput, average end-to-end delay, routing overhead, normalized routing load (NRL), packet drop and packet loss metrics. The protocols considered are DSR, AODV and DSDV. The first two protocols fall under reactive whereas the third one is a proactive protoco...

This paper proposes Mobile Ad-Hoc Network Based Child Monitoring with DSDV routing. The aim of this paper is to reduce child abduction in general or maternity hospital, which is important in Indonesia because of many cases of child abduction, appeared in those hospitals. The method of child tracking and monitoring of this paper is using Mobile Ad-Hoc Network with DSDV routing to substitute GPS ...

High-speed Wireless LANs based on 802.11 technologies are becoming increasingly ubiquitous. IEEE 802.11n is the last standard toward achieving higher speeds and aims to enhance 802.11 for higher throughput. Few works studied 802.11n medium access control (MAC) layer, but unfortunately, effects of higher physical rates is sti ll unknown to the upper layers and especially routing layer of these n...

MANET (Mobile Adhoc Network) is a self organizing and self configuring network without the need of any centralized base station. In MANETs, the nodes are mobile and battery operated. As the nodes have limited battery resources and multi hop routes are used over a changing network environment due to node mobility, it requires energy efficient routing protocols to limit the power consumption, pro...

A mobile ad hoc network (MANET) is a group of wireless mobile nodes dynamically shaping a provisional network devoid of the use of any existing network infrastructure or centralized management. In MANETs, security is the major challenge due to the dynamic topology which is because of the mobility of the nodes. In this paper, we propose a design and develop a secure methodology incorporated with...

Mobile Ad-hoc Network (MANET) is a network which is capable of autonomous operations and operates without base stations and without centralized administration. Nodes cooperate to provide services. In the mobile ad hoc network every node is router as well as host. They support dynamic topology and have limited energy and computed resources. Ad hoc routing protocols like as Dynamic source routing...
