Electronic device with wireless path selection capability
First Claim
1. A method for establishing a wireless network connection by a wireless interface unit of a device, the method comprising:
- establishing at least one wireless link with one or more peer devices to join a wireless network of the one or more peer devices, wherein the at least one wireless link is established based on one of;
an on-demand path-selection protocol, proactive path selection protocol, and a hybrid path selection protocol;
receiving at least one portal announcement comprising a link metric indicative of a request to establish the wireless network connection from a device via the one or more peer devices;
detecting a change in a network topology of the wireless network based on processing of the link metric;
switching from a current path selection protocol to a new path selection protocol based on the detection of the change in network topology, wherein the new path selection protocol is selected based on a pre-defined rule, from amongst the on-demand path-selection protocol, proactive path selection protocol, and a hybrid path selection protocol.

Abstract
A portable encoded information reading (EIR) terminal for incorporation in a data collection system can comprise a terminal module communicatively coupled to a wireless interface module via a wired interface. The terminal module can include a central processing unit (CPU), a memory, and an encoded information reading (EIR) device. The wireless interface module can include a microcontroller, a memory, and at least one wireless communication interface. The wireless interface module can establish one or more wireless links with one or more peer EIR terminals, to join a wireless network which is collectively formed by the peer EIR terminals. The wireless interface module can receive or transmit beacons containing at least an identifier of a path selection protocol which is used for unicast, multicast and broadcast frame transmission within the wireless network.

11. A method for establishing a wireless network connection by a wireless interface unit of a first device, the method comprising:
-
receiving, from a second device, a portal announcement comprising a link metric indicative of a request to establish the wireless network connection, wherein the request is received at a wireless interface module of the first device, via a plurality of peer devices; re-broadcasting, upon receiving, the received portal; and periodically transmitting a route request message to discover one or more routes from the second device to a destination device, wherein the route request message is transmitted to at least one of the plurality of peer devices receiving the re-broadcasted portal announcement. - View Dependent Claims (12, 13, 14, 15)

16. A method for establishing a wireless network connection to a device via a network of one or more peer devices from a wireless interface unit of a first device, comprising:
-
establishing, by a wireless interface module, at least one wireless link with one or more peer devices to join a wireless network of the one or more peer devices; receiving at least one portal announcement indicative of a request to establish a connection from a second device via the one or more peer devices; and caching, upon the receiving of the portal announcement, a network address of the device from which the portal announcement request is originated. - View Dependent Claims (17, 18, 19, 20)
