Emergency networks, especially networks of disaster recovery, have been the focus of active research in many countries. That is due to the broad impact of disasters' frequent occurrences, and casualties. The Hybrid Network Emergency Communication (HNEC) protocol is proposed [9] which establishes a heterogeneous network disaster recovery (NDR) that includes non-IP systems to achieve emergency requirements...
Wireless sensor networks are often deployed in harsh environments, where the adversary is able to capture certain sensors. Once a sensor is compromised, the adversary can easily replicate it and deploy several replicas back into the network for further malicious activities. Although a number of protocols have been proposed to tackle such node replication attacks, few of these schemes are suitable...
Low-latency data delivery is an important requirement for achieving effective monitoring through wireless sensor networks. When sensor nodes employ duty cycling, sending a message along the shortest path, however, does not necessarily result in minimum delay. In this paper, we first study the lowest latency path problem, i.e., the characteristics of a path with minimum delay that connects a source...
With the increasing interest in the application of wireless ad hoc networks, the demand for providing QoS in such applications also grows. Particularly, in sensor and actor networks, providing certain delay bounds is crucial for the actors as they perform their actions based on the received data from sensors. The usefulness of the content from sensors is based on its timeliness. In this paper, we...
We study the problem of secure routing in wireless sensor networks where the sensors and the sink can move during the execution of remote monitoring applications and communication is not necessarily directed towards the sink. We present a new routing protocol that builds upon a collection of mechanisms so that the integrity and confidentiality of the information reported to the controlling authorities...
Data dissemination is an essential task in large-scale wireless sensor networks (WSNs). While performing data dissemination under a battery power constraint, energy efficiency is a key design factor of routing protocol because deployed nodes cannot be replaced or recharged after deployment and a dead node may lead to the partition of whole networks. As a solution for the efficient data dissemination,...
