Abstract

Emergency data which mean something happened in sudden need to be dealt with timely, otherwise will bring very serious consequences. To ensure the low-delay routing of emergency data, a novel graded routing strategy, dynamic adaptive cooperative routing (DACR) is proposed in this paper. This scheme extends the LEACH protocol to enable the multi-hop transmissions among clusters by incorporating a cooperative MISO scheme into hop-by-hop transmissions. Simulation results show that DACR significantly decreases end-to-end delay by approximately 30% for emergency data compared to the regular data. Lifetime is prolonged compared to the multi-hop LEACH.
