A mobile random network (MANET) is a self-organizing cordless network composed of mobile nodes and requires no set system. Routing is a crucial task in MANET as the nodes are moving. So, the principal goal of your ad hoc routing standard protocol is to determine the correct and reliable way between any couple of nodes with minimal overhead. Routing overhead is an essential metric. In the event ...
This paper evaluates three routing strategies for wireless sensor networks: source, shortest path, and hierarchical-geographical, which are the three most commonly employed by wireless ad-hoc and sensor networks algorithms. Source routing was selected because it does not require costly topology maintenance, while shortest path routing was chosen because of its simple discovery routing approach ...
13 BSTRACT Mobile Ad hoc Networks are infrastructure less networks. Nodes themselves do routing and forwarding functions. Topology changes due to node movement. Frequent changes in topology leads to more route breaks. This in turn leads to reduction in Packet delivery Ratio (PDR). It is desired that routing protocols should select stable paths i.e. which are less likely to break. In this work, ...
Routing packets within a large-scale wireless sensor network (WSN) without storage overhead and routing table updates is a challenging problem. With a large number of sensors the overhead plays a significant role in the scalability of the routing protocol. To avoid this communication overhead, WSN routing demands new and efficient methods for routing packets. Remove or reduce this overhead, the...
Quality-of-Service (QoS) routing is indispensable to real-time applications on integrated services packet-switching networks. However, existing QoS-routing schemes based on either request ooding or link-state dissemination are not e cient in terms of their message overhead and/or operational cost. This paper proposes a QoS-routing algorithm with bounded ooding which not only dramatically reduce...
Traditional routing protocols in Mobile Ad hoc Network (MANET) send periodic messages to realize the changes in topology. Sending periodic messages cause overhead. Compared to proactive routing protocols, reactive routing protocols can cause less overhead. Broadcasting can cause broadcast storm problem .To discover the route better than broadcasting methodology rebroadcast can done with the hel...
Opportunistic Data Forwarding (ODF) has drawn much attention in mobile adhoc networking research in recent years. The effectiveness of ODF in MANET depends on a suitable routing protocol which provides a powerful source routing services. PLSR is featured by source routing, loop free and small routing overhead. The update messages in PLSR are integrated into a tree structure and no need to time ...
During route discovery of mobile ad hoc network, broadcasting of route request and route reply packets are the essential operations for finding the path between two ends. In such situations, intermediate node which may or may not belongs will participate in route discovery process, update routing table and rebroadcast the route discovery packets again to its neighboring nodes. Finally optimal p...
Many wireless ad hoc routing protocols have been proposed in the literature. Researchers are comparing and improving these protocols before standard routing protocols are defined. In this paper, we present a framework for wireless ad hoc routing protocols based on the concept of a relay node set (RNS). This framework facilitates the comparison, design, and improvement of wireless ad hoc routing...
To improve the throughput and transmission quality of routing protocols for Wireless Mesh Networks, this paper presents a cross-layer routing protocol MCL-AODV for the wireless Mesh backbone networks. The protocol takes the quality of MAC layer link, node queue congestion degrees and wireless transmission distance into account through the cross-layer operating system, to optimize the routing se...
