SUMMARY In wired networks, broadcast and multicast transmissions can be easily achieved by data link layer (layer 2). Nevertheless, it is a big challenge to safely transfer broadcast or multicast data frames over multi-hop mobile ad hoc networks (MANETs) due to the high bit error rate, the high collision probability and the lack of acknowledgment. Additionally, most of MANET's routing protocols...

In duty-cycled wireless sensor networks, deployed sensor nodes are usually put to sleep for energy efficiency according to sleep scheduling approaches. Any sleep scheduling scheme with its supporting protocols ensures that data can always be routed from source to sink. In this paper, we investigate a problem of multi-hop broadcast and routing in random sleep scheduling scheme, and propose a nov...

Several routing algorithms for mobile ad hoc networks (MANETs) have been proposed in the recent past [1], [2], [3]. With the exception of a few, these protocols (i) involve all nodes in the route management process, (ii) rely on the use of broadcast relays for route computation, and (iii) are primarily reactive in nature. Related work [4], [5] has shown that the capacity utilization in ad hoc n...

In many traditional On Demand routing algorithms in Ad hoc wireless networks, a simple flooding mechanism is used to broadcast route request (RREQ) packets when there is a need to establish a route from a source node to a destination node. The broadcast of RREQ may lead to high channel contention, high packet collisions, and thus high delay to establish the routes, especially with high density ...

Vehicular Ad hoc Network (VANET), a subclass of mobile ad hoc networks (MANETs), is a promising approach for the intelligent transportation system (ITS). The design of routing protocols in VANETs is important and necessary issue for support the smart ITS. The key difference of VANET and MANET is the special mobility pattern and rapidly changeable topology. It is not effectively applied the exis...

In wireless ad hoc networks, due to the dynamic topology changes, multi hop communications and strict resource limitations, routing becomes the most challenging issue, and broadcasting is a common approach which is used to alleviate the routing problem. Global flooding is a straightforward broadcasting method which is used in almost all existing topology-based routing protocols and suffers from...

We present the source-tree adaptive routing (STAR) protocol and analyze its performance in wireless networks with broadcast radio links. Routers in STAR communicate to its neighbors their source routing trees either incrementally or in atomic updates. Source routing trees are specified by stating the link parameters of each link belonging to the paths used to reach every destination. Hence, a r...

As mobile ad hoc networks (MANETs) are emerging as important components in critical and large-scale applications, it is crucial to develop MANET routing mechanisms with provably low complexity. In this paper, we give a tutorial overview of the efficient use of elementary node clustering and route request broadcast mechanisms for low-complexity MANET routing. We explain these mechanisms with ill...

Vehicular Ad hoc Network (Vanet) is one of the emerging technologies to support safety, traffic monitoring and comfort related services. Vanet is a subclass of MANET but its topology changes rapidly and network gets disconnected frequently. The prevailing routing protocol of MANET is very much applicable to Vanet. Because of its frequently disconnecting routes it is difficult to design an effic...

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 ...
