This chapter explores the design of wireless sensor networks for applications in precision agriculture. A short review of developments in precision agriculture and recent applications of wireless sensor networks in the area is presented. The authors present their design of medium access control and network layer protocols exploring the challenges and opportunities associated with the design of such a networked system. The physical layer in their network allows multiple power modes in both receive and transmit operations. The MAC layer employs these multiple power modes to implement a novel wake-up synchronization mechanism to reduce the energy overhead. The network layer ensures reliable collection of data while balancing the energy consumption among the nodes. Finally, the authors present an analytical approach to model the behavior of the MAC protocol developed and compare it against the duty-cycle based S-MAC protocol. The results are also confirmed using simulations.

Wireless sensor networks are designed to remotely monitor physical or environmental attributes such as temperature, pressure, light, sound, etc. They generally comprise embedded system units consisting of sensing, processing, and communication units inside them. Such Wireless sensors can be deployed in extreme conditions like deep forests, high or low-temperature areas, industrial setup, etc. where continuous manual surveillance is not possible. In this paper, Wireless Sensor networks have been discussed in detail. Their architecture, operational characteristics, and challenges associated with setting up and managing the Wireless Sensor Networks have been discussed.

Wireless Sensor Networks (WSN) is a rising innovation and step by step it is pulling in the consideration of scientists with its testing qualities and differentiated application space. The more scientists attempt to grow encourage cost and vitality proficient figuring gadgets and calculations for WSN, the all the more difficult it gets to be to fit the security of WSN into that obliged environment. Be that as it may, security is vital to the accomplishment of applying WSN. Along these lines, commonality with the security parts of WSN is basic before planning WSN framework. In this paper, we review the condition of craftsmanship in securing remote sensor systems. We audit a few conventions that give security in sensor systems. Additionally, this study records the notable assaults at the Network layer of WSN.
