Abstract
AbstractThis paper presents a communication framework for end‐to‐end seamless connectivity improvement in IEEE802.11‐based wireless home networks. The proposed communication framework incorporates the following two things: a new concept of wireless home network architecture and a new routing technique in an effort to improve wireless communication coverage and end‐to‐end seamless packet delivery respectively. First, the proposed wireless home network architecture based on the End‐to‐end Seamless multi‐hop COnnectivity based on Dual‐mode (ESCOD) integrates infrastructure and ad hoc modes in an IEEE 802.11‐based wireless home network. Second, the Virtual Link Routing (VLR) technique, a kind of ad hoc routing protocols working on the layer 2.5, provides mobile nodes with end‐to‐end seamless connectivity and packet delivery. We compare the performance of VLR with two prominent on‐demand routing protocols for Mobile Ad hoc Networks (MANET), Dynamic Source Routing (DSR) and Ad hoc On demand Distance Vector (AODV), in the ESCOD‐based wireless home network. Experiments show that our communication framework incorporating the VLR technique in the ESCOD‐based wireless home network architecture yields efficient performance in terms of the low failure rate of packet transmission, fast packet transmission time, network throughput, and a wider coverage area of wireless home networks.
