Nowadays more requirements for wireless sensor networks are utilized to military, science and our daily life gradually, however the sink mobility is still bottleneck problem in a number of WSN application scenarios. In some fields like environmental monitoring, the solution is an especially urgent request. In this paper we propose Patrol Grid Protocol (PGP), a sink mobility supported route protocol for environmental monitoring which builds on a previously developed routing protocol called TWO-Tier Data Dissemination (TTDD). We prove that PGP can be more suitable for urgent events and query-driven mode than TTDD. The description of mechanisms and simulation are presented firstly, then we evaluate the performance of the new protocol and analyze the overhead and delay. PGP is a more applicable protocol for environmental monitoring.
