ABSTRACT
Firmware Over-the-Air (FOTA) update technology is required to keep the software of the massively deployed Wireless Sensor Network (WSN) devices up to date. However, when there are many nodes in a WSN and the cellular network connects the server and the WSN, the traditional method of transferring data directly from the server to the end node can be costly. We propose a Two-Phase FOTA Dissemination Scheme to address the communication cost problem by reducing traffic between WSN and external networks. This demonstration shows that the two-phase update reduces traffic between the external network and the WSN.

Configuring node status in a two-phase tightly integrated mode for wireless sensor networks
In wireless sensor networks, one of the main design challenges is to save severely constrained energy resources and obtain a long system lifetime. Low cost of sensors enables us to initially deploy a large number of sensor nodes in a very high density. ...
Relay Node Placement in Wireless Sensor Networks
A wireless sensor network consists of many low-cost, low-power sensor nodes, which can perform sensing, simple computation, and transmission of sensed information. Long distance transmission by sensor nodes is not energy efficient since energy ...
Sensor scheduling for p-percent coverage in wireless sensor networks
We study sensor scheduling problems of p-percent coverage in this paper and propose two scheduling algorithms to prolong network lifetime due to the fact that for some applications full coverage is not necessary and different subareas of the monitored ...
