We study a random access scheme for satellite packet communication with intentional interference. A modified Slotted ALOHA protocol is used with interferer power sensing to achieve maximum user throughput. For a malicious interferer who ignores the control parameters broadcast by the satellite (such as the back-off parameter), we show that the degradation of channel throughput is inversely proportional...
Free-space optical networks have serious block erasures due to atmospheric turbulence and require an entirely new network architecture from Layer 1 to Layer 4 for big data flows.
This paper identifies regimes of high connectivity and the associated throughput, delay, and energy per bit scaling performance of a power-limited infrastructureless wireless network. Infrastructureless wireless networks are a key strategic technology for future military communications. In their current state, their utility for mission critical applications is limited by their susceptibility to disconnection...
TCP does not perform well in networks with stochastic channels, with links that randomly drop packets or have long outages. Diversity routing has been proposed to improve TCP's performance in these networks. In diversity routing, a sublayer between TCP and the network replicates each transmitted packet and sends the multiple copies along parallel paths. As long as at least one of the copies reaches...
1TCP is a popular transport layer protocol. The performance of TCP is known to be unsatisfactory in wireless network, due to high bit error rates or drop outs. Employing error correction at the transport layer can alleviate the problem to some extent. We make three contributions in this paper. First, we optimize the efficiency of repetitive codes. In particular, we propose a good estimate on throughput...
