In urban vehicular wireless environments, several vehicles can send warning messages and so every vehicle within the transmission range will receive the broadcast transmission, possibly rebroadcasting these messages to other vehicles. This increases the number of vehicles receiving the trafficwarningmessages.Hence, redundancy, contention, and packet collisions due to simultaneous forwarding (us...

This paper provides a scheme to reduce the cost to distribute multimedia content to a set of nearby mobile peers, which we call chums. One peer, called the proxy, downloads multimedia content via a telecommunication link, and distributes it (which we call chumcast) to the ad hoc network formed from the set of nearby peers. Each peer in the ad hoc network takes turns serving as a proxy. Every pe...

A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. The proposed Adaptive Energy-efficient On-demand Distance Vector routing (AEODV) Protocol for MANETs that is based on the Ad-hoc On-demand Distance Vector (AODV). The AEODV makes significant reduction in t...

In mobile ad hoc networks (MANETs)[1], a mobile station (MS) can communicate with nodes outside of its transmission range by employing intermediate nodes as relays. To find a path to a specific destination node, the source node broadcasts route request packets that are forwarded to all other nodes. A simple flooding scheme is employed in AODV [2], where every node rebroadcasts these route reque...

Recapturing and rebroadcasting of images are common attack methods in insurance frauds face identification spoofing, an increasing number detection techniques were introduced to handle this problem. However, most them ignored the domain generalization scenario scale variances, with inferior performance on shift situations, normally exacerbated by intra-domain inter-domain variances. In paper, w...

ZigBee provides a simple and reliable solution for the low-cost networks. The ZigBee ad hoc on-demand distance vector (Z-AODV) could use the global shortest path for data transmission by flooding the routing quest when necessary. However, the current routing algorithms cannot fully address the energy consumption issue. In this paper, we propose a directional broadcasting algorithm in routing di...

Routing is one of the challenging issues in Mobile Ad hoc NETw orks (MANETs). Broadcasting is the fundamental and eff icient data dissemination mechanism for route discovery in reactive routing protocols of Mobile Ad hoc NETw ork (MANET). This causes the problem called the broadcast storm problem w hich results in redundant retransmission and adds to routing overhead. There are many approaches ...

Adhoc on demand distance vector routing protocol(AODV) is specially designed for mobile adhoc networks with reduced overhead using Expanding Ring Search technique. But energy consumption should also be considered in MANET due to battery constrain of the nodes. In this paper, we choose an energy efficient route discovery process for AODV based on Expanding Ring Search(ERS). We want to saves ener...

Mobile Adhoc Network (MANET) is a set of self-configuring mobile hosts, equipped with a CSMA/CA (carrier sense multiple access with collision avoidance) transceiver, that may communicate, move freely independently and any time without any base station support. The broadcasting is inevitable operation in MANET and commonly used for route discovering. The flooding technique used normally for broa...

Most reactive routing protocols in MANETs employ a random delay between rebroadcasting route requests (RREQ) in order to avoid “broadcast storms.” However this can lead to problems such as “next hop racing” and “rebroadcast redundancy.” In addition to this, existing routing protocols for MANETs usually take a single routing strategy for all flows. This may lead to inefficient use of resources. ...
