This On-demand route discovery mechanism of reactive protocols based on flooding of route request packets faced serious excursion of “broadcast storm”. Moreover, frequent path breakages are experienced due to link failures, as an impact of time varying characteristics of radio channel and/or node mobility. In this paper Channel Quality Adaptive Gossip Flooding mechanism for Ad hoc On-demand Distance...
We consider the problem of maximizing the alphafairness utility over the downlink of a heterogeneous wireless network (HetNet) by jointly optimizing the association of users to transmission points (TPs) and the activation fractions of all TPs. Activation fraction of each TP is the fraction of the frame duration for which it is active, and together these fractions influence the interference seen in...
We consider an energy harvesting system where the fixed size battery of the transmitter is recharged with certain probability at each channel use. For this setup, we explicitly characterize the optimal online energy management strategy for maximizing the long-term throughput under different assumptions on the availability of channel state information. We show that in the case of no fading, the amount...
In wireless networks, where each node transmits independently of other nodes in the network (the ALOHA protocol), the expected delay experienced by a packet until it is successfully received at any other node is known to be infinite for the signal-to-interference-plus-noise-ratio (SINR) model with node locations distributed according to a Poisson point process. Consequently, the information velocity,...
This paper addresses the benefits of introducing exclusion regions around both transmitters and receivers in D2D wireless networks. Such exclusion regions offer protection from interference at the expense of a sparser spatial reuse of spectrum, bringing about a tradeoff whose resolution entails optimizing the size of the exclusion regions as function of relevant system parameters. Our figure of merit...
