Throughput analysis and routing security discussions of mobile access coordinated wireless sensor networks

In this paper, we analyze the throughput of a novel mobile access coordinated wireless sensor network architecture (MC-WSN) under single path and multipath routing. The obtained throughput expressions highlight the trade-off between achieving high throughput performance and improving the network security strength. The results reveal the importance of: (i) minimizing the number of hops in maximizing the throughput, and (ii) adopting routing diversity in combating malicious attacks and network failure conditions. We control the number of hops in data transmission through optimal topology design and active network deployment achieved by the mobile access point (MA). To combat routing attacks, we propose a secure routing path selection approach, and show the impact of the proposed approach on improving the throughput performance under malicious attacks.
