Broadcast is a common communication means in mobile ad hoc network or wireless sensor network. In directed diffusion protocol, broadcast is used to disseminate interest, discover routing path and repair the routing path. However, straightforward broadcast scheme (such as flooding) may result in serious broadcast storm problem, especially with respect to large densely deployed wireless sensor ne...

We consider the problem of multihop broadcast over adaptively duty-cycled wireless sensor networks (WSNs) where neighborhood nodes are not simultaneously awake. We present Hybrid-cast, an asynchronous and multihop broadcasting protocol, which can be applied to low duty-cycling or quorum-based duty-cycling schedule where nodes send out a beacon message at the beginning of wakeup slots. Hybridcas...

Broadcasting is an information dissemination process in communication networks whereby a message, originated at any node of a network, is transmitted to all other nodes of the network. In c-broadcasting, each node having the message completes up to c transmissions to its neighbors over the communication lines in one time unit. In a kfault tolerant c-broadcast network, the broadcasting process c...

This paper proposes the use of repetitive broadcast as a way of augmenting the memory hierarchy of clients in an asymmetric communication environment. We describe a new technique called “Broadcast Disks” for structuring the broadcast in a way that provides improved performance for non-uniformly accessed data. The Broadcast Disk superimposes multiple disks spinning at different speeds on a singl...

We derive the capacity region for a broadcast channel with intersymbol interference (ISI) and colored Gaussian noise under an input power constraint. The region is obtained by first defining a similar channel model, the circular broadcast channel, which can be decomposed into a set of parallel degraded broadcast channels. The capacity region for parallel degraded broadcast channels is known. We...

This paper presents the architecture and implementation of a multi-service streaming system for broadcast of MPEG4 elementary streams. The proposed system promotes the use of the push channel model for information distribution [1]. The system architecture accommodates two main layers for broadcast service management and media delivery. The broadcast service management layer uses the publisher-s...

In this paper, we propose a new token-based distributed algorithm for total order atomic broadcast. We have shown that the proposed algorithm requires lesser number of messages compared to the algorithm where broadcast servers use unicasting to send messages to other broadcast servers. The traditional method of broadcasting requires 3(N − 1) messages to broadcast an application message, where N...
