The vehicle has no parking assist system and takes much time to wander around aimlessly to find parking spaces near the destination. In recent years, how to help a driver find parking spaces by the Vehicle Ad Hoc Networks (VANETs) is an important problem. This paper proposed a novel direction-base recommendation algorithm (DRA) to reduce both the search time for parking and the competition of parking...
A new 1,10‐phenanthroline (Phen) derivative, 3,8‐bis(5‐methylthiophen‐2‐yl)‐1,10‐phenanthroline (PHT1), has been synthesized and fully characterized including by single‐crystal X‐ray structure analysis. The electron‐donating effects of the two 5‐methylthiophene groups lead to distinctive fluorescence emission enhancement on complexation with Zn2+ compared with non‐emissive Phen. However, PHT1 shows...
The mobility of underwater sensor nodes makes the network topology inconveniently controlled and slowly changed. Thus, in order to enable underwater sensor networks to work more effectively, it is necessary for us to periodically detect the coverage rate and redeploy nodes to non-coverage areas. In this paper, we take the lead in introducing the redeployment issue in underwater sensor networks. In...
