....receiver. We show that this basic channel access scheme can provide a higher throughput than single channel CSMA CA for the same available channel capacity, due a reduced number of packet collisions. 2 Related Work Multichannel random access protocols were first explored for wired networks in [1], where it was shown that the use of multiple channels with the same aggregate capacity can improve the throughput of CSMA protocols. In a wired medium, carrier sensing is perfect as the signal level is considered to be the same at all points in the network. However, collisions may still occur due ....

....central control or via additional message communication and synchronization. None of them are viable in an ad hoc setting. 2 MULTICHANNEL CSMA PROTOCOL Multiple channel CSMA protocols are not entirely new. They were shown to be more efficient than their single channel counterparts in wired LANs [2]. Packet transmission over multiple random access channels in wireless networks was also explored in [16] where multi channel slotted ALOHA [1] was analyzed. A multichannel MAC protocol was presented in [8] for application in a class of ad hoc networks termed as Reconfigurable Wireless Networks. ....

....there has not been any demonstration of improved throughput of wireless networks by breaking up the available wireless medium into several channels and using a suitable access protocol for reducing the probability of collisions, which is the goal of this paper. We extend the concept presented in [2] to the wireless scenario to design a new multi channel CSMA scheme that provides soft channel reservation. In [2] it is shown that for a wired LAN with N channels, use of carrier sensing to randomly select one of the idle channels for transmission has a throughput advantage that increases with ....

....a point to point topology is usually modeled with a graph, a bus based topology may be modeled with a hypergraph [4] In a hypergraph, every edge is associated with a subset of vertices, rather than exactly two vertices, as in a graph. Bus based topologies are often used in multichannel networks [26], in which the set of nodes is connected by parallel communication channels. The channels may be physically separate or may be multiplexed on a single high capacity medium. 1 In this paper, the multicast problem is studied for a class of multichannel networks that use so called staircase ....

....offers no fault tolerance [36] Using multiple channels is one method to increase the capacity of the network and make it more resistant to failures. Multichannel networks also allow more gradual system growth, as a system may start with a small number of channels and add more channels over time [26]. Multichannel networks may be classified as either single hop or multiple hop. If the topology is single hop, then every node can transmit directly to every other node. If the topology is multiple hop, then a message may have to be transmitted on, and switched among, multiple channels before ....
