Wireless sensor networks are harshly restricted by storage capacity, energy and computing power. So it is essential to design effective and energy aware protocol in order to enhance the network lifetime. In this paper, a review on routing protocol in WSNs is carried out which are classified as data-centric, hierarchical and location based depending on the(More)
Wireless Sensor Networks find various applications in different fields. Sensor nodes are small, low-cost and low-powered communication devices. Hence designing a network with low power consumption is a critical issue in WSN. Different schemes are projected for achieving low power communication under short network range. To reduce the use of power and(More)
Wireless Sensor Networks (WSNs) consist of large number of sensor nodes with limited battery power and storage capacity. So it is essential to design effective and energy aware protocols in order to prolong the network lifetime. PEGASIS is one of the well-known chain-based routing protocols for improving energy efficiency, based on a chain-based greedy(More)
School food policies and services have the potential to influence the food practices and eating behaviours of adolescents which in turn may affect their lifestyles and health in adulthood. The aim of this qualitative investigation was to describe the opinions of adolescents, their parents, nutrition educators and school principals about the prevailing food(More)
Extensive use of wireless sensor networks have started due to the wide variety of applications of them including military, health, space exploration, vehicular movement, environment monitoring, disaster management etc. Hence different protocols should be designed based on the QoS requirements of the application. Also sensor nodes have limited storage(More)
