We present the Express Broadcast Network (EBN), a network used for quick and reliable broadcast of control messages in multicomputer networks. The EBN can be implemented with a single extra wire per network link and with minimal extra hardware at each routing node. However, it provides very fast broadcast mechanisms that take advantage of all redundancy in the network to deliver messages regard...

The network layer of ad hoc networks is prone to attacks. Insertion of false routing information is inherently easy unless the routing messages are authenticated. Hence, protection of the routing protocol is a prerequisite for a reliable network service. The wireless broadcast media calls for bandwidth e¢ cient solutions. This paper proposes a hybrid protection scheme for the ad hoc Optimized L...

A new approach to broadcast in wormhole-routed three-dimensional (3D) mesh networks is proposed. The approach extends the concept of dominating sets from graph theory by accounting for the relative distance-insensitivity of the wormhole routing switching strategy and by taking advantage of an all-port communication architecture, which allows each node to simultaneously transmit messages on diie...

Vehicular Ad-hoc Networks (VANETs) are known as a special type of Mobile Ad-hoc Networks (MANETs) specialized in vehicular communications. These networks are based on smart vehicles and basestations, which share data by means of wireless communications. To route these information, a routing protocol is required. Since the VANETs have a particular network features as rapidly changeable topology,...

The Directed Flood-Routing Framework (DFRF) for wireless sensor networks that allows the rapid development of application specific routing protocols based on directed flooding is introduced in this paper. Flood-routing protocols are probabilistic methods that make only the best effort to route data packets. The presented family of protocols can route regular sized data packets via broadcast mes...

(ABSTRACT) In order to save energy consumption in idle states, low duty-cycled operation is widely used in Wireless Sensor Networks (WSNs), where each node periodically switches between sleeping mode and awake mode. Although efficient toward saving energy, duty-cycling causes many challenges , such as difficulty in neighbor discovery due to asynchronous wakeup/sleep scheduling, time-varying tra...

Scalable and efficient broadcast is essential to the large-scale computing infrastructures such as PlanetLab and Grids. By exploiting the greedy routing mechanisms of Distributed Hash Table (DHT), existing DHTbased broadcast algorithms suffer from the limitations of scalability and load balancing, incurring high construction and maintenance overhead for a distributed broadcast tree (DBT). This ...

Wireless sensor networks are inherently plagued by problems of node failure, interference to communications from environmental noise and energy-limited sensor motes. These problems pose conflicting issues in the design of suitable routing protocols. Several existing reliable routing protocols exploit message broadcast redundancy and hop count as routing metrics and their performance trade-offs ...

This paper proposes a novel cooperative scheme combining distributed space-time block code (STBC) at physical layer, multiple access protocol at medium access control (MAC) layer and opportunistic routing without complicated routing algorithm for achieving high reliability for vehicle-to-vehicle (V2V) communications. The proposed scheme can reduce interference and collision, and achieve reducin...
