An analysis of unreliability and asymmetry in low-power wireless links
Marco Zúñiga Zamalloa, Bhaskar Krishnamachari
Article No.: 7
Experimental studies have demonstrated that the behavior of real links in low-power wireless networks (such as wireless sensor networks) deviates to a large extent from the ideal binary model used in several simulation studies. In particular,...
Tiny-sync: Tight time synchronization for wireless sensor networks
Suyoung Yoon, Chanchai Veerarittiphan, Mihail L. Sichitiu
Article No.: 8
Time synchronization is a fundamental middleware service for any distributed system. Wireless sensor networks make extensive use of synchronized time in many contexts (e.g., data fusion, TDMA schedules, synchronized sleep periods, etc.). We...
Bounds on coverage and target detection capabilities for models of networks of mobile sensors
Article No.: 9
In this article we analyze the capabilities of various models of sensor networks with the Boolean sensing model for mobile or stationary sensors and targets, under random or optimal placement, independent or globally coordinated search, and...
A diffusion model for packet travel time in a random multihop medium
Article No.: 10
We consider a wireless network in which packets are forwarded opportunistically from the source towards the destination, without accurate knowledge of the direction that they should take. A Brownian motion model that includes the effect of packet...
This article proposes the minimum power configuration (MPC) approach to power management in wireless sensor networks. In contrast to earlier research that treats different radio states (i.e., transmission/reception/idle) in isolation, MPC...
Coverage breach problems in bandwidth-constrained sensor networks
Maggie X. Cheng, Lu Ruan, Weili Wu
Article No.: 12
Recent research in sensor networks highlights the low-power mode operation of sensor networks. In wireless sensor networks, network lifetime can be extended by organizing sensors into mutually exclusive subsets and alternatively activating each...
