Chapter 9Challenges

Chapter 8 presented a brief overview of the unique challenges of ad hoc wireless sensor networks. In this chapter we consider these problems in detail. In addition to describing the challenges, we contrast the characteristics and capabilities of existing sensors with the properties of traditional networking environments. By understanding the unique aspects of ad hoc networks, the protocols presented in Chapter 10 become more understandable.

Existing protocols for traditional networks would work fine with ad hoc networks if their characteristics were not different. In many cases, ad hoc networks have requirements that mirror those of existing wired networks. Requirements such as routing, addressing, medium access control, security, ...
