Embodiment

[0046] The networking and the routing algorithm of the mobile phone ad hoc communication network CellNet based on bluetooth technology described in the present embodiment comprise the following steps:

[0047] (a) Networking stage: connect the node to the Bluetooth network, and update the neighbor nodes in the contactlist of the node;

[0048] (b) Update phase: update the information of each neighbor node in the contactlist of the current node in real time;

[0049] (c) Sending stage: The current node sends ordinary data packets or system data packets to the next node. The system data packets refer to data packets related to network access and heartbeat. The data packets related to network access and heartbeat are related to the handShake protocol mentioned later. (Handshake protocol) is related to the heartbeat protocol (heartbeat protocol). Ordinary data packets refer to data packets other than system data packets, such as ordinary text information, system information, etc.;...

Abstract

The invention discloses a networking and routing algorithm based on a Bluetooth technology for a mobile phone ad hoc communication network CellNet. The method comprises the following steps: (a) networking stage: making a node access a Bluetooth network, and updating neighbor nodes in a contactlist of the node; (b) updating stage: updating information of the neighbor nodes in the contactlist of the current node in real time; (c) sending stage: sending a normal text message or a system message to a next node by the current node; (d) routing stage: when one node receives a data packet forwarded by another node, checking whether the data packet is already processed or not through a processed data packet table, if so, discarding the data packet, and otherwise carrying out a next step; and (e) receiving stage: making corresponding response actions by the next node according to different types of received messages. Through adoption of the method, the routing overhead can be reduced; the network burden is relieved; and network congestion is avoided.

Description

technical field [0001] The invention relates to the field of wireless ad hoc networks, in particular to the networking and routing algorithm of CellNet, a mobile phone ad hoc communication network based on bluetooth technology. Background technique [0002] At present, there are many studies on wireless ad hoc networks, such as "Research on the Improvement of Ad-Hoc Network Routing Protocol and Research on Wireless Mesh Network Routing Technology", which introduces many algorithms, including DSDV, OLSR, DSR, AOVD, TORA, LAR, GRSR, etc. However, these algorithms have some disadvantages, such as DSDV and OLSR algorithms, which are based on table-driven routing and need to maintain the routing of the entire network at each node. When the network becomes larger and larger, the size of the table at each node will decrease. It is getting bigger and bigger. When maintaining this table, it also needs to send its own node information to the nodes in the network, which increases the ...
