“…Previous sensor networks that did not implement end-to-end reliability exhibited data yield of 20 ∼ 60% [18], [19] and thus fail to meet the requirements of gas leak monitoring. Reliable collection protocols [20]- [22] employ local data caching and end-to-end retransmissions to improve data yields. Most of the reliable collection protocols aim to energy efficiency rather than low latency [21]- [23], whereas SPEED [24] focuses on real time without considering reliability.…”

GasNet is a sensor network for real-timely monitoring the gas leak in residential buildings, in order to efficiently protect the buildings from gas leak explosion. GasNet provides low-latency and reliable gas leak ALARM message delivery in complicated RF environments. It does so through ROAP, a novel opportunistic forwarding mechanism considering link correlation. ROAP leverages a hop tree in opportunistic forwarder list selection to ensure the shortest hops to the sink. Furthermore, link correlation is used to obtain more accurate forwarding probability and to achieve fast retransmission. We implement the prototype of GasNet in campus testbed and evaluate its performance via extensive experiments. The experiment results show that ROAP achieves 100% gas leak ALARM message delivery in low latency.

A New Fuzzy Algorithm For Improving Quality Of Service In Real Time Wireless Sensor Networks

A wireless sensor network comprise a large number of cheap sensors as nodes. These sensors used for data collection and transmition to a central node(sink), are distributed in packed formats in an intended wide area of operation. One of the vital issues in these networks, is their energy constraints which directly affects the network life span. In real time wireless sensor networks (RWSN), not only energy constraints but data delivery time has a vital role in network successful operations as well as data validation. In real time programs, quality of service parameters such as delays must be reduced to a minimum. Reduction of packet losses to increase reliability of data deliveries is another issue in these networks. In this article, a new routing algorithm with fuzzy technique for improving quality of service in RWSN, is presented. The main objectives of this technique are two folds. The first is reduction of energy consumption which results in an increase in the network operations life span and the second is to meet a defined end-to-end delay and hence increasing reliability by reducing number of packet losses considerably. By using different fuzzy parameters and if-then rules, each node can make a decision to choose its next step for routing towards destination (sink). Simulation results show that our proposed new protocol considerably reduces energy usage in the network as well as guaranting the quality of service and noticeable improved performance in comparison with SPEED and THVR.

“…This feature allows transmission in real-time or nearreal-time because the time for reconfiguration is less than 30 ms. Additional 15 ms are necessary for the sensor to wake up and another 15 ms for the channel access. Practical applications show that these time intervals are up to 10 times bigger [9,21,22]. The channel capacity is usually up to 100 kbps.…”

Abstract. The aim of this paper is to present an idea of the platform for enhanced living environment that will allow flexible and reliable use of cloud computing and sensor networks for highly customized services and applications. The architecture is based on sensors using IEEE 802.15.4 and zigbee protocols. Furthermore, the access to the cloud could be done by any available wired or wireless technology. We propose an application layer service using peer port for reliable and scalable data transmission. The presented solution is dynamic, flexible and conforms to the health and home automation standards.
