Embedded Software Design for WSNs,d data transmission and reception. The embedded software architecture for WSNs is given with the Jennic ZigBee and the Contiki 6LowPAN as two examples. Examples of both analog and digital sensor driver developments are introduced. The implementation of establishing WSNs is illustrated by adopting an

Routing Technologies in WSNs,or reactive routings or based on network structures or network protocol operations. After briefly introducing general routing protocols, the Ad hoc On-Demand Distance Vector (AODV) routing protocol and the cluster-tree routing methods are described in detail. These are commonly used by ZigBee networ

Optimization of Sink Node Positioning, include an infinite solution space, the involvement of a huge number of sensor nodes, the different network architectures and routing protocols in use, different sensor node capabilities, and different application needs. This chapter categorizes the optimal sink node positioning problem in terms of

Interference of WSNs with IEEE 802.11b Systems,ber of wireless technologies such as 6LowPAN, ZigBee, Bluetooth, and WiFi are all using the 2.4?GHz free-licence frequency band, the possibility of interference between them has to be addressed in any design and implementation of a WSN. This chapter initially identifies the causes of interference in

Sensor Data Fusion and Event Detection,lude the sensors’ internal errors, a harsh environment in which the sensors are deployed, and data loss occurring during wireless transmission. Sensor data fusion consists of three steps, data pre-processing, data mining, and data post-processing. This chapter discusses data pre-processing and data

WSN Security,s them attractive targets for unscrupulous individuals to subvert, in an attempt to gain access to the WSNs and/or disrupt the interactions of users with both the networks and subsequently with their environment. Consequently, providing effective security is crucial for the successful adoption and o

Building Fire Safety Protection: SafetyNET,on about the building, occupants and/or the location of the hazard. They do not know whether it is safe to enter and how to most efficiently deal with the hazard. This chapter introduces a completed UK government funded project ‘Secure Adhoc Fire and Emergency safety NETwork (SafetyNET)’, which meet
