Abstract:

[Background] Currently, wireless sensor networks play an increasingly prominent role in a variety of emergencies, such as emergency protection and rescue. However, the survivability of wireless sensor networks in the emergency environment also faces enormous problems and challenges. [Objective] In order to extend the network survival time and enhance the level of information services, it is necessary to efficiently utilize limited system resources according to the dynamic changes of the emergency environment, for fully utilizing the functions and effects of wireless sensor networks. Based on the target demand of network survivability, the survival status, service demand, and performance bottleneck of wireless sensor networks in emergency scenarios are analyzed, and then several key technologies and effective measures to enhance the survivability of wireless sensor networks in the emergency environment are explored. [Methods] Firstly, the survivability characteristics and service needs of wireless sensor networks in the emergency response environment are summarized, and open issues and technical challenges in survivability of wireless sensor networks in the emergency response environment are comprehensively analyzed. Secondly, the survivability-related research works on wireless sensor networks at home and abroad are investigated. On this basis, a number of technical problems for efficient organization, operation, and maintenance of the wireless sensor networks in the emergency environment are explored and feasible solutions are presented in terms of network architecture, survivability enhancement techniques, and survivability assessment methods. [Conclusions] Network survivability technology has become one of the research hotspots in the large-scale deployment and application of wireless sensor networks. This paper focuses on ensuring the on-demand provision of key services in wireless sensor networks through efficient resource utilization and adaptive allocation in the complex and ever-changing emergency environment. It is expected to provide valuable solutions to construction of flexible and robust heterogeneous wireless sensor networks with high survivability in emergency situations.
