Abstract—In recent years the wireless communication networks combined with the wired networks have made tremendous progress with both the upgrade of cellular networks to support wide area data access and the widespread deployment of IEEE 802.11 based local area networks. Although both wired and wireless provides advantages and disadvantages in their own unique way it is the integration of these networks that we can reap the real technological reward from both. Although there is extensive research ongoing on individual networks in isolation it is the combination of these networks where the information highway will be open to all and in this case the need for architecture that fulfills the demands of the users in all scenarios. The various heterogeneous wireless networks architectures proposed are Unified Cellular Ad hoc Network (UCAN), (Integrated Cellular Ad hoc Relay (iCAR) and Scalable Proxy Routing (SPR) and multiple hop cellular networks. Although each has their unique design and protocol we discuss them and also point out their security weaknesses in any attack.

Index Terms—Heterogeneous networks, UCAN, iCAR,SPR, security weaknesses.
