This directory contains "TKN15.4", a platform-independent IEEE 802.15.4-2006 MAC implementation. The code is still under active development, but most of the functionality described in the standard is implemented. The MAC itself is platform-independent, but it requires (1) a suitable radio driver, (2) Alarms/Timers with symbol precision and (3) some "platform glue" code (defining guard times, etc.). Currently the only supported platform is TelosB (however: without additional hardware support the timing is not standard compliant). Status 6/16/08 -------------- missing functionality: - security (not planned) - GTS (not planned) - non-beacon-enabled mode - PAN ID conflict resolution - multiple indirect transmissions to the same destination - documentation Implementation -------------- MAC implementation: tinyos-2.x/tos/lib/mac/tkn154 MAC interfaces: tinyos-2.x/tos/lib/mac/tkn154/interfaces CC2420 driver: tinyos-2.x/tos/chips/cc2420_tkn154 TelosB "platform glue" code: tinyos-2.x/tos/platforms/telosb/mac/tkn154 Example applications: tinyos-2.x/apps/tests/tkn154 Copyright --------- This work was supported by the the European Commision within the 6th Framework Project 2005-IST-5-033406-STP (ANGEL project) Author: Jan-Hinrich Hauer /* * Copyright (c) 2008, Technische Universitaet Berlin * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * - Redistributions of source code must retain the above copyright notice, * this list of conditions and the following disclaimer. * - Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. * - Neither the name of the Technische Universitaet Berlin nor the names * of its contributors may be used to endorse or promote products derived * from this software without specific prior written permission. * * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR * A PARTICULAR PURPOSE ARE DISCLAIMED.
