Suppose mA location-unknown sensors out of all n sensors can be located by a localization algorithm A, then ωA = mA/n is defined to be the efficiency of the algorithm A. Different from the traditional trilateration technique using 3 neighbors (hence referred to as 3 neighbor algorithm, or 3NA for short), in 2004 Barbeau et al [1] proposed an algorithm, referred to as 2N+aB for short, which can locate...
In this paper we propose a multihop code distribution protocol RECD which is reliable and efficient.We use a epidemical algorithm to guarantee the haleness and integrality of the distribution.To extend the life of network, reducing energy consumption and improving radio channel utilization, we propose a sender selection mechanism that make tradeoff between energy and influence.Further we introduce...
This paper presents the design and implementation of controller which based on a lightweight sensor-oriented network protocol. The controller is packed as AVALON standard peripheral for further application. It can be treated as a normal intellectual property core in project design, so that the operation on it is simplified as reading or writing on register. The test results show that the controller...
