We consider a network with n nodes distributed uniformly in a unit square. We show that, under the protocol model, when ns = Ω (log(n)1+α) out of the n nodes, each act as source of independent information for a multicast group consisting of m randomly chosen destinations, the per-session capacity in the presence of network coding (NC) has a tight bound of Θ(√n/ns√mlog(n)) when m = O(n/log(n)) and...
We introduce a new multiuser diversity concept with which multiple transmitters can communicate without causing significant interference to each other. The new scheme, called Opportunistic Interference Management (OIM), significantly reduces the feedback required in distributed Multiple-Input Multiple-Output (MIMO) systems, and requires an encoding and decoding complexity that is similar to that of...
The throughput capacity of wireless ad hoc networks is derived when the traffic is heterogeneous but the node distribution is homogeneous. For the heterogeneous traffic we consider two types of traffic in the network, namely, unicast and data gathering communications. There are k sources that send different data to a single node and the rest of n-k nodes in the network participate in unicast communications...
