Summary form only for tutorial. Recent proliferation of wireless devices had considerably increased the need for networking and provisioning intercommunication between these devices for various applications. Broadly, the wireless networks can be classified into two categories. The cellular networks and wireless local area networks can be termed as infrastructure-based wireless networks. The second category, termed as infrastructureless wireless networks include mobile ad hoc networks and sensor networks. Mobile ad hoc networks (MANETs) have use in battlefields, disaster recovery areas, intercommunication between islands or in difficult terrains, and conferencing with any infrastructure support. Sensor networks have a wide range of applications ranging from monitoring environments, sensitive installations, and remote data collection and analysis. In this tutorial we will have an in-depth view of the issues related to mobile ad hoc networks and sensor networks. The outline of our tutorial follows. Recently, in addition to adaptive signal processing (ASP), iterative signal processing (ISP) has been extensively investigated as it can significantly improve the performance of the receiver under interference-limited channel environments. One example is the turbo equalizer that can improve the performance significant by properly mitigating intersymbol interference (ISI). ISP is different from ASP in some aspects. ISP is based on off-line processing. Hence, it results in a relatively long processing delay and large memory requirement. However, as hardware and computing power have been significantly improved, the difficulties will not be obstacles to ISP becoming popular. The main idea of the proposed tutorial is to introduce up-to-dated ISP techniques in wireless communications context.
