Network Protocols & Algorithms (Issue : 1) (Volume : 7)
Monitoring older bridges using Wireless Sensor Networks (WSNs) has had a lot of attention in recent years. In much of this research tasks like sensor data processing, environment states and events decision making are done by a remote server. A Structural Health Monitoring (SHM) application using WSNs to provide the data collection necessary for rapid structural assessment after an event such as a natural disaster has been simulated in this paper. Efficient MAC and routing protocols must be designed for the proposed application to offer a guarantee for the reliability of the data delivered from source nodes to a sink. The number of delivered reports, delay and the lifetime of the network are considered in the proposed application. As a result, a new cross layer protocol based on MAC and routing protocols is designed and simulated for SHM application taking different scenarios into consideration and results are presented in this paper. Simulation results show that the proposed protocol increases performance of the target application, in varies scenarios.

Network Protocols and Algorithms (Issue : 3) (Volume : 6)
Wireless video sensor networks have been a hot topic in recent years; the monitoring capability is the central feature of the services offered by a wireless video sensor network can be classified into three major categories: monitoring, alerting, and information on-demand. These features have been applied to a large number of applications related to the environment (agriculture, water, forest and fire detection), military, buildings, health (elderly people and home monitoring), disaster relief, area and industrial monitoring. Security applications oriented toward critical infrastructures and disaster relief are very important applications that many countries have identified as critical in the near future. This paper aims to design a cross layer based protocol to provide the required quality of services for security related applications using wireless video sensor networks. Energy saving, delay and reliability for the delivered data are crucial in the proposed application. Simulation results show that the proposed cross layer based protocol offers a good performance in term of providing the required quality of services for the proposed application.

Using Wireless Sensor Networks (WSNs) in healthcare systems has had a lot of attention in recent years. In much of this research tasks like sensor data processing, health states decision making and emergency message sending are done by a remote server. Many patients with lots of sensor data consume a great deal of communication resources, bring a burden to the remote server and delay the decision time and notification time. A healthcare application for elderly people using WSN has been simulated in this paper. A WSN designed for the proposed healthcare application needs efficient MAC and routing protocols to provide a guarantee for the reliability of the data delivered from the patients to the medical centre. Based on these requirements, A cross layer based on the modified versions of APTEEN and GinMAC has been designed and implemented, with new features, such as a mobility module and routes discovery algorithms have been added. Simulation results show that the proposed cross layer based protocol can conserve energy for nodes and provide the required performance such as life time of the network, delay and reliability for the proposed healthcare application.

Wireless Sensor Networks (WSNs) detect events using one or more sensors, then collect data from detected events using these sensors. This data is aggregated and forwarded to a base station(sink) through wireless communication to provide the required operations. Different kinds of MAC and routing protocols need to be designed for WSN in order to guarantee data delivery from the source nodes to the sink. GinMAC has been simulated for real time applications, where energy saving, delay and reliability need to be considered. Mobility module for GinMAC has been implemented. According to the simulation results, GinMAC can be applied for real time applications in both mobile and static scenarios. However, GinMAC needs some improvement for its performance in term of energy saving and also efficient routing protocols needs to be designed to cooperate with GinMAC in order to provide the required performances in the proposed applications. Our future plans are given at the end of this paper
