  Future wireless networks will generally be characterized by heterogeneity in architecture, protocols and air interfaces. The wireless networking scene is dominated by two distinct networking platforms: (a) cellular networks, which passed through multiple generations -1G, 2G and 3G, and (b) Wireless Local Area Networks (WLANs) championed by the IEEE 802.11 networks. Recent trends indicate that 3G networks and WLANs will co-exist to offer public wireless broadband services to end users. The two platforms offer characteristics that complement each other perfectly.

  The 3G cellular systems such as Universal Mobile Telecommunications System (UMTS) and Code Division Multiple Access (cdma2000) will support real-time and non-real-time multimedia services with data rates from 144 kb/s to 2 Mb/s with wide coverage and nearly universal roaming. However, the costs of acquiring the necessary radio spectrum and the required network equipment upgrades are very high. This is in contrast to WLAN systems such as IEEE 802.11 a/b/g, which provide affordable services and bit rates surpassing those of 3G systems, up to 11 Mb/s with 802.11b and 54 Mb/s with 802.11a/g. However, the coverage offered by WLANs is quit limited and lacks roaming support.

  The complementary characteristics of 3G cellular systems (slow, wide coverage) and WLAN (fast, limited coverage) make it attractive to integrate these two technologies to provide ubiquitous wireless access. The purpose of integrating 3G systems and WLANs is to make it possible to use the best parts of both systems. High bandwidth WLANs are used for data transfer where available and 3G systems can be used where WLAN coverage is lacking. Development and standardization efforts are currently underway for defining suitable architectures for 3G/WLAN integration. However, designing a network architecture that efficiently integrates 3G systems and WLAN is a challenge task that needs a lot of research efforts.

In this special issue, we intend to publish a collection of high quality papers by world leading researchers that present state-of-the-art research in the area of 3G/WLAN integration.


Topics of interest include, but are not limited to:


1. Mobility management

2. Seamless vertical handoff techniques between 3G and WLAN

3. Location management techniques

4. Architecture design scenarios for integrating 3G and WLAN systems

5. Network selection criteria

6. Bandwidth adaptation

7. Consistent quality of service across 3G and WLAN

8. Adaptive quality of service provisioning

9. Performance evaluation studies

10. Pricing and Billing Issues

11. Standardization activities
