Rule-Based Sensor Data Aggregation System for M2M Gateways

Rule-Based Sensor Data Aggregation System for M2M Gateways

To reduce the server load and communication costs of machine-to-machine (M2M) systems, sensor data are aggregated in M2M gateways. Aggregation logic is typically programmed in the C language and embedded into the firmware. However, developing aggregation programs is difficult for M2M service providers because it requires gatewayspecific knowledge and consideration of resource issues, especially...

Rule-Based Data Aggregation in a Distributed Diagnostic System

an efficient protocol for data aggregation in wireless sensor networks

sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...

Sensor Data Collection through Unmanned Aircraft Gateways

Current addressing and service discovery schemes in mobile networks are not well-suited to multihop disconnected networks. This paper describes an implementation of a highly mobile ad-hoc network (MANET) that may never experience end-to-end connectivity. Special gateway nodes are described which are responsible for intelligently routing messages to their intended destination(s). These gateway n...

EIDA: An Energy-Intrusion aware Data Aggregation Technique for Wireless Sensor Networks

Energy consumption is considered as a critical issue in wireless sensor networks (WSNs). Batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. An efcient solution to improve energy consumption and even trafc in WSNs is Data Aggregation (DA) that can reduce the number of transmissions. Two main challenges for DA are: (i)...
