Sensor networks are typically sensor or radio event driven. Exploiting this property we propose a novel wake-on sensor network design. In this context we have designed a new sensor platform called TelosW. The wake-on sensing capability of TelosW lets designated sensors wake up the microcontroller (MCU) only on occurrence of some event with preconfigurable threshold. TelosW also includes the CC1101...
This paper proposes a comprehensive routing protocol (CRP) based on the ant colony algorithm for the applications of Wireless Sensor Network (WSN). It is a protocol taking both the lifetime of network and the arrival rate of data packet into account. In CRP, multiple paths are found between source and destination, and sub-optimal paths are used occasionally referring to the probabilistic forwarding...
AODV (Ad Hoc On-Demand Distance Vector) protocol is an on-demand protocol specialized for ad hoc network and it has been used as a mesh routing in 6LoWPAN (IPv6 over IEEE 802.15.4). In order to adapt to the hardware sources especially energy source restrictions of 6LoWPAN, we propose S-AODV (Sink Routing Table over AODV) routing, a new AODV implementation designed to provide benefits in terms of traffic...
Routing is a key technique for wireless sensor networks (WSN). In order to improve the efficiency of routing in large-scale WSN, we propose Sink Routing Table (SRT) routing protocol, a routing protocol for WSN, in this paper. In SRT protocol, nodes aggregate data and use energy aware neighbor selection to route packets towards the target along an optimal path, each common node has no need to maintain...
This paper proposes a routing protocol for the applications of Wireless Sensor Network (WSN). It is a protocol based on the PEGASIS protocol but using an improved ant colony algorithm rather than the greedy algorithm to construct the chain. Compared with the original PEGASIS, this one, PEG-ant, can achieve a global optimization. It forms a chain that makes the path more even-distributed and the total...
