This work discusses the adaptation of group-oriented messaging and chat technology for operation in serverless, multicast-capable mobile wireless architectures. The main goals are to allow group messaging and chat sessions to fragment/coalesce, operate through disrupted TCP conditions, and improve bandwidth utilization when multicast is available. In addition, the solution demonstrates proxying and...
In this paper, we study the fairness problem for downlink traffic in multi-hop wireless backhaul networks with selfish nodes, including Transit Access Points (TAPs) and the gateway. Unlike the transmission of uplink traffic in which transit packets are dropped at intermediate TAPs, almost all downlink link traffic is dropped at the gateway. Therefore, we design an incentive-based mechanism where the...
In wireless multi-hop networks, when an end host would like to communicate with external wired hosts, data packets are to be transmitted at first to a gateway node which is connected to both a wireless multi-hop network and a wired network. When there are multiple candidate gateways to be connected, a wireless host should select one gateway as its own default gateway. One possible and simple way is...
In wireless communication, Mobile Ad Hoc NETwork (MANET) is a set of mobile nodes that are dynamically and randomly located in such a manner that the wireless link among nodes are often changing due to MANET dynamic features. In this MANET environment, if a device wants to connect to Internet, it must establish a communication with an Internet Gateway. The network performance between mobile nodes...
The development of mobile ad hoc systems have considerably emphasized the need for a better understanding of the factors that influence the systemspsila performance, i.e., mobility patterns, radio propagation, traffic characteristics and their interrelations. Depending on the context where the system is being used-whether at work, at home, or in some means of transportation-there will be various applications...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
