This letter drives a novel inequality expression on source-to-sink average BER (S2S-ABER) for multi-hop communication in a network. The obtained expression is less complex and can be implemented on computationally constraint devices, such as sensor nodes. Moreover, it has been applied to wireless sensor networks to determine the SNR limitations such that S2S-ABER does not exceed a threshold value...
In this paper, we consider a sequential binary hypothesis testing framework in wireless sensor networks. We study the effect of sensor censoring on network performance in terms of the average error probability and average number of observations required until a global decision is made. The detection process is mathematically modeled as a random walk process with two absorbing barriers. We resort to...
We present the ε-outage capacity in the low signal-to-noise ratio (SNR) regime of an incremental relaying network. The network consists of one source, one destination, and two half-duplex relays. The one-bit feedback from the destination node is considered to be imperfect and is modeled as binary symmetric channel. The basic idea is that in each block only one terminal transmits depending on the feedback...
