We present here a fundamental understanding of the capacity of wireless ad hoc networks. Under the assumption that all interference is essentially regarded as noise, we try to answer the question: “What is the lower bound on network capacity under a certain power assignment and nodal distribution?” We give two quantitative lower bounds: one is measured in bps (bits per second), the other is measured...
We propose a multihopping decode and forward relaying protocol for two-stage Gaussian relay networks with half-duplex nodes. We analytically show that the achievable rates in suitably defined strong and weak interference regimes are close to the cut-set bound.
We address a two-user decentralized interference channel with static non-frequency selective channel gains. Both users are unaware of each other's code-books and there is no central controller to manage the allocation of resources between the two users. As multiuser detection is not possible, the conventional scheme of transmitting a continuous stream of i.i.d. symbols from Gaussian codebooks by each...
This paper studies the throughput scaling of wireless networks over channels with random connections, in which the channel connections are independent and identically distributed (i.i.d.) according to a common distribution. The channel distribution is quite general, with the only limitations being that the mean and variance are finite. Previous works have shown that, when channel state information...
In this paper, we compute the throughput capacity of wireless ad hoc network when nodes are capable of multi-packet reception (MPR) under the physical model. Earlier results show that the optimistic protocol model [1] provides a tight bound of Theta(D(n)) where D(n) and n denote the decoding range and the number of nodes in the network respectively. On the other hand, the throughput capacity under...
