Nowadays, wireless sensor networks (WSNs) emerge as an active research area in which
challenging topics involve energy consumption, routing algorithms, selection of sensors …

Many Internet of Things (IoT) networks are created as an overlay over traditional ad-hoc
networks such as Zigbee. Moreover, IoT networks can resemble ad-hoc networks over …

Staff shortages and an increasingly aging population are straining the ability of emergency
departments to provide high quality care. At the same time, there is a growing concern about …

This paper presents several proposed and existing smart utility meter systems as well as
their communication networks to identify the challenges of creating scalable smart water …

We consider the problem of running RPL on top of the IEEE 802.15. 4 MAC layer-the two
layers operate over two different structures, a directed acyclic graph in the case of RPL and …

This paper proposes and implements an early warning and monitoring system for rainfall-
induced landslide (named as EWMRIL) with a case study at the Nam Dan landslide …

This paper proposes a mobility support scheme for 6LoWPAN. In the scheme, the control
information interaction for the mobile handoff is achieved in the link layer, and the routing of …

Abstract IEEE 802.15. 4-2006 represents a widely used standard for multihop wireless
sensor networks. However, the standard exploits a tree structure in the MAC layer, which …

This paper proposes a scheme for constructing an Internet Protocol (IP) version 6 over low-
power wireless personal area networks (6LoWPAN) wireless sensor network based on a …

Recently, Micro-Electro-Mechanical-Systems (MEMS) based accelerometers become a
good candidate for replacing the geophone and inclinometer in landslide monitoring. By …
