Abstract

A method for multihop packet trasmissions in a wireless network involves establishing a multihop route through the wireless network. After establishment of the multihop route, transmission protocol parameter are altered to minimize delays for transmissions over the multihop route and at least one packet is transmitted over the multihop route according to the altered transmission protocol parameters. In a first embodiment, the altering of the transmission protocol parameters includes setting a NAV value at each node of the multihop route for a duration of the packet transmissions over the route. In an alternative embodiment, multihop packets are assigned a higher QoS value.
