ÐAll-to-all communication is one of the most dense communication patterns and occurs in many important applications in parallel computing. In this paper, we present a new all-to-all broadcast algorithm in all-port meshes and tori. The algorithm utilizes a controlled message flooding based on a novel broadcast pattern, which ensures a balanced traffic load in all dimensions in the network so tha...

Broadcast and broadband communications have undoubt- edly become a part of today’s social life. Accessibility of content of interest to the audience at any place and at any time regardless of the type of content consumer device can have an effective contribution to the desire of the audience to use of the broadcast content. The HD and Ultra HD qualities, the desire for demand-driven application...

Enhancing route request broadcasting protocols constitutes a substantial part of recent research in mobile ad-hoc network (MANET) routing. We suggest a novel approach to modify route request broadcast based on node caching. The intuition behind node caching is that the nodes involved in recent data packet forwarding have more reliable information about its neighbors and have better locations (e...

In this paper, we propose an efficient geo-routing aware MAC protocol (GOAL) for underwater acoustic networks. It smoothly integrates self-adaptation based REQ/REP handshake, geographic cyber carrier sensing, and implicit ACK to perform combined channel reservation and next-hop selection. As a result, it incorporates the advantages of both a geo-routing protocol and a reservation-based medium a...

In recent years, Mobile Ad-hoc Networks (MANETs) is one of the popular research areas due to low cost to employ the network, self-organization, freedom of location, and no base stations. Broadcast and data aggregation are crucial operations in MANETs. Due to the high mobility of nodes and the transmission distance, nodes may change their positions rapidly and thus not only change the network to...

The low quality of wireless links leads to perpetual packet losses. While an acknowledgment mechanism is generally used to cope with these losses, multiple retransmissions nevertheless occur. Opportunistic routing limits these retransmissions by taking advantage of the broadcast nature of the wireless channel: sending packets to multiple receivers at once, and only then, based on the outcome, c...

The multi-hop wireless network has drawn a great deal of attention in the research community. Within the long period after it was proposed, the routing and forwarding operations in the multi-hop wireless network remain to be quite similar to those in the multi-hop wired network or the Internet. However, all the data transmission over the wireless medium in the wireless networks is by broadcasti...

As deployment of sensor networks are recently expanding, a variety of services based on sensor network have been introduced. Nevertheless, problems such as network bandwidth reduction, collision occurrence and performance deterioration due to broadcasting of message in large scale networks have become main challenges. Above all, prolonging of battery lifetime becomes primary challenge to overco...

In this paper we propose multicast (Mcast) routing architecture that uses basic trees and their neighboring MNs (NMN) in ad-hoc network. The basic trees are generated based on hop-counts from mobile nodes (MN) toward arbitrary base node (BN). The NMNs of a specific MN on a basic tree are upper, lower or peer MNs that 1-hop away from it and controlled by other basic trees. These NMNs identify on...
