Multi-hop wireless networks (such as ad-hoc or sensor networks) consist of sets of mobile nodes without the support of a pre-existing fixed infrastructure. For the purpose of scalability, ad-hoc and sensor networks may both need to be organized into clusters and require some protocols to perform common global communication patterns and particularly for broadcasting. In a broadcasting task, a so...

tv broadcasting right is one of the main sources of financial income for football clubs in the world. however, this right has not been legalized in iran yet and has caused many serious problems for iranian football clubs. the aim of this study was to investigate legal gaps and obstacles and to provide strategies to improve the relationships between football clubs and islamic republic of iran br...

The paper concerns time-efficient k-shot broadcasting in undirected radio networks. In a k-shot broadcasting algorithm, each node in the network is allowed to transmit at most k times. Both known and unknown topology models are considered. For the known topology model, the problem has been studied before by Ga̧sieniec et al. [14], who established an upper bound of D + O(kn1/(k−2) log n) and a lo...

Broadcasting is a process in which an individual has an item of information which needs to be transmitted to all of the members in a network (which is viewed as a connected graph). -broadcasting is a variant of broadcasting in which each processor can transmit the message to up to of its neighbors in one time unit. Another variant of broadcasting is the concept of m-time-relaxed broadcasting, w...
