With an ever-increasing population growth in cities around the world, continuous production
of all kinds vehicles by manufacturers, and the number of vehicles on the roads will only …

This paper presents and evaluates two principles for wireless routing protocols. The first is
datapath validation: data traffic quickly discovers and fixes routing inconsistencies. The …

Within the construction industry, accident statistics indicate that there are fatalities and
serious injuries in confined spaces due to exposure to hazardous environment. A review of …

Current data collection protocols for wireless sensor networks are mostly based on quasi-
static minimum-cost routing trees. We consider an alternative, highly-agile approach called …

Construction workers who are exposed to hot and humid environments are at high risk of
heat stress. Excessive exposure to such environments can result in occupational illnesses …

Existing systems for traffic information acquisition have high costs and low scalability owing
to their characteristics such as large size, wired power supplies, and wired communication …

Highway construction work zones are hazardous environments characterized by a dynamic
and limited workspace. A host of interactions between workers, passing commuter vehicles …

Abstract The Collection Tree Protocol (CTP) is a well-know protocol that provides a reliable
collection service for wireless sensor networks. In this report, we describe our …

The network topology has a significant impact on the performance of collection protocols in
wireless sensor networks. In this paper, we introduce an unobtrusive methodology to …

Many wireless sensor network applications rely on the availability of a collection service to
route data packets towards a sink node. The service is typically accessed through …
