Current Hindrances in WSNs
Sharief Oteafy, Hossam S. Hassanein · 2014
This chapter elaborates a number of hindrance domains in wireless sensor network (WSN) research. More importantly, it highlights the voids that grew as a result of recent WSN literature. Many innovations have contributed to the current advancements in WSNs. These include recent advances in MEMS that aid node design, high-end/low power transceivers that boost communication capabilities and a large spectrum of digitized sensors that enable significant WSN penetration in a plethora of domains. In an attempt to improve WSN performance, especially in terms of resilience to failures and errors in operation, over-deploying nodes in the field is widely adopted. With an enormous address space (2128) and the ability to encompass almost all objects uniquely, much deliberation is taking place about the future of IPv6 in WSNs. However, as appealing as it is to simply assign IP addresses to SNs for enabling web services, many challenges deem it a distant goal.
